Instruments for testing water quality. Xiaomi TDS tester review – How clean do we drink water? Device for determining the quality of drinking water

The quality of water consumed by humans is under constant control.

The parameters that water must meet are set by the current SanPiN, as well as by order No. 162 / pr, issued on 04.04.14 by the Ministry of Construction of the Russian Federation.

In order to determine the indicators mentioned above, special instruments are used. Some of them are discussed in this article.

Oximeters

This is the name of the devices that allow you to determine the physical content of oxygen dissolved in water. Depending on the model, the devices are used as industrial enterprises as well as in household plots.

The most popular in our country today are the models below.

Extech DO600+

A kit that includes a waterproof device. The product is designed to measure the degree of concentration of oxygen dissolved in water, both in the laboratory and in the field. The design of the gas analyzer is equipped with a 5-meter extension and has a special weighted protective mount. This allows you to determine the desired performance in open water and in vessels. The oxygen level can be determined as percentage(0-200), and in concentration fractions (0-20 mg/l). The device has a built-in adaptation function for the height of the measurement site (0 - 6096 m) and salinity (0 - 50 * 10 -3).

The product has a built-in memory that allows you to save the results of the last 25 measurements. If during operation there is an increase in the consumption of the built-in battery, the device automatically performs self-calibration.

According to current regulations, the water resistance of the device must be at least IP57. The standard equipment of the device includes:

• DO - electrode;
• membrane spare cap;
• touch protective cap;
• electrolytic batteries of autonomous power supply 4 * 3V type CR2032;
• carrying strap.

Instrument dimensions 36*176*41 mm. Weight 110 g.

The device is designed to measure the indicators of oxygen dissolved in water, as well as to diagnose the suitability of a particular reservoir for fishing and fish breeding.

Another direction of using the device is to determine the sanitary condition of natural and artificial reservoirs from the point of view of protecting the natural environment in terms of such an indicator as the level of oxygen dissolved in water.

Measurements are required to be carried out at regular intervals. This is due to the fact that the concentration of oxygen in water is a variable value (depending on the water layer, season, time of day, etc.).

Measurements can be taken as a percentage, in mg/l or ppm.

Before starting work, the instrument is calibrated against ambient air.

Multi-parameter device U-50 for determining the quality of water

A series of these portable analyzers has the ability to simultaneously measure and display up to eleven parameters. Convenient to work and robust construction puts the devices of this model range among the most effective in monitoring ground water, drainage channels and open reservoirs. The instrument has intuitive menu systems.

All analyzers of the specified model range have sensors and a built-in control unit. The instrument provides a wide range of functions to choose from. The length of the connecting cable is about 10 meters, which allows measurements at different depths. The built-in GPS navigator shows on the map the point where measurements are taken.

The measurement results are entered into memory and can be processed by a PC using a special program. The device allows you to perform the following measurements:

• pH (mV), pH(pH);
• redox (ORP) potential;
• (COND) - electrical conductivity;
• (OD) – dissolved oxygen;
• (TDS) is the total content of solids dissolved in water;
• (SAL) - mineralization, expressed by electrical conductivity;
• (SG) is the specific gravity of sea water;
• (TURB) - turbidity (LED is used as a light source, the method of scattering light forward at 300m);

Working parameters:

Salinometer (TDS-meter) TDS - 3

Designed to determine the hardness of water. Used to analyze the presence of salts in water. The device allows you to measure the conductivity of water, the degree of its purification and quality.

This salt meter measures the amount of solid particles dissolved in a fixed volume of water (Total Dissolved Solids).

The capabilities of the device allow you to quickly determine the temperature of water, its quality and hardness, regardless of the source from which the sample was taken.

Allows you to calculate the amount of metal salts dissolved in water.

Water is the source of life on our planet. And human health largely depends on its quality. This explains the importance of controlling the quality of the water you use.

Water is an integral part of every person's life. We use it every day while cooking, washing dishes, taking a shower or bath. Not always such a liquid entering an apartment or house meets safety standards. It can harm human health or even endanger life. "Wrong" water can in a short period of time disable plumbing, destroy the integrity metal pipes and ruin clothes in the wash.

We have already written an article on this topic. If someone is not familiar with it yet, then be sure to read it. To do this, go to this . In today's article, I want to talk about the range of the Russian market for measuring instruments for water quality analysis. We will learn what an aquatester is, what types exist, and consider the most popular models.

Aquatester for measuring the level of PH

A PH water tester is a device that measures the amount of hydrogen in a liquid. These devices at home are able to determine the level of acidity in drinking water. Increased values ​​of this parameter are harmful to human health. Contribute to the formation of scale, damage to household appliances and plumbing fittings. There are professional models designed for laboratory research, but for home use, you can buy a portable aquatester. He will let you do detailed analysis water. The error of such devices is only 0.02%. The price of these models starts from 1000 rubles. For functional samples will have to pay about 5 thousand. To get acquainted with the range of aquatesters for measuring PH, you can follow this link .

ORP tester

The human body is 90% fluid. One of the main factors affecting our general state and health in general, is the quality of the water. Aquatester ORP is a device that determines the redox potential in any liquid. The usefulness of water for a person depends on this parameter. Every time we drink, the body receives an additional portion of acids and alkalis that contribute to proper processing. useful substances and stabilizing the acid-base environment. The ORP indicator in the human body should vary from -50 to -100 millivolts. The device will measure the specified coefficient. In "good" water, it should not exceed 7.0. The cost of water testers for measuring ORP starts from 2800 rubles for a household appliance. For a professional tester, you will need to pay from 10 to 20 thousand rubles. An approximate range can be found on this link.

TDS tester

TDS tester, saline meter or water hardness meter are versatile devices that can carry out a comprehensive analysis of the liquid. They are great for home use. With the help of such a device, you can find out the hardness of water, electrical conductivity, approximate chemical and mineral composition, as well as determine the presence of impurities and salts. Modern models contain a thermometer and adjust the readings depending on the temperature of the liquid. The advantages of such devices are versatility, compactness, ease of use and display information. Aquatester of this type is able to analyze the liquid within 3 minutes. The cost of models starts from 2500 thousand rubles, and reaches 15 thousand. The range can be viewed at this link .

Outcome

I want to say that the cost of these devices, in my opinion, is not high. If you buy an aquatester once and check the water that flows from the tap, you can be calm about its quality. If the liquid does not meet the established standards, you should think about purchasing filters or cleaning systems.

If you are not familiar with the article about "Cabinet water treatment systems in an apartment or house", you can read it by clicking .

I hope my article today was useful and understandable to you. Write in the comments if you are sure about the quality of your water?! And what do you think, is it worth buying a water tester for the home, if so, which one?

The problem of clean water exists in almost every home. Someone purchases and installs special filters, while someone just wants to check the condition of the liquid, so they buy a water tester. This device makes it possible to find out if the water is suitable for home use and whether cleaning is necessary.

Tester Tasks

Today, a water tester is not such a popular device, since personal filters can also control the quality of water. But it is worth noting that it will not be possible to find an ideal model among these filters, because they all collect particles of solid matter after long-term use, which can soon get into the water. Most often, people who use cheap filters that do not perform their functions from the first day get hit.

If suddenly the water became suspicious bad smell and color, then a water quality tester will help to find out exactly about its problematicity. As a rule, there is a sewer smell, a taste of chlorine or rotten eggs, but people pay attention to this quite rarely.

Principle of operation

The water tester is designed to measure the amount of heavy particles in a liquid (PPM from 0 to 1000). The higher the value, the more dangerous the water to use. The acceptable norm is PPM from 100 to 300.

Filters can only clean up to a level of 0-50. If the level has reached 600 PPM, then the water will have a strange taste.

Top Models

A water tester will help you check the quality of the filter. Any model provided below will serve its owners long years no problem. With such devices, you can easily find out the state of drinking water, liquid in the pool or aquarium.

Xiaomi Mi TDS Pen

One of the most famous and respected is the Xiaomi Mi TDS Pen water tester. Despite the fact that initially this production was exclusively engaged in the production of software and smartphones, today under its brand you can find excellent devices for home use.

Xiaomi is a water quality tester that has long become a necessary device for people living not only in large cities, but even in villages. The device determines the content and amount of such substances:

• heavy metals - copper, zinc, chromium;
• organic components (ammonium acetate);
• inorganic salts (calcium).

A water tester, the cost of which reaches 500 rubles, measures everything as accurately as possible. That is, if it shows a value of 250 PPM, then this means that in millions of particles there are exactly 250 particles of unnecessary substances that worsen the condition of the liquid.

Xiaomi's amazing water tester is capable of measuring quantities ranging from 0 to 1000+ PPM. Deciphering the result is not so difficult:

• from 0 to 50 - ideally pure water;
• from 50 to 100 - a fairly pure liquid;
• from 100 to 300 - the usual allowable rate;
• from 300 to 600 - hard liquid;
• from 600 to 1000 - rather hard water, which is practically undrinkable, although the risk of poisoning is low;
• more than 100 PPM - liquid dangerous for use.

Finding a use for a high quality analyzer is fairly easy. Most often it is used to check the quality of water where the filter has already worked. Xiaomi TDS is a water tester that allows its owners to find out in time about the poor performance of cartridges and replace them.

It looks like the most common electronic thermometer, closed on both sides with special caps. On top are the batteries that are included in the kit, and below are two titanium probes.

You can turn the device on or off by pressing a single button. To analyze the liquid, the device must be lowered into a container of water, and then pay attention to the display, which is located on the side and displays the result.

You can also calibrate the device without much effort. To do this, you can take water intended for injection, sold in pharmacies. It is always ultra-pure and is therefore an excellent reference for calibration.

Before measuring, it should be remembered that the result is affected by the temperature of the liquid. In order to take into account this parameter, the device is able to measure the degree of water heating.

Reviews

Many buyers who have been using the device regularly for quite a long time claim that it is almost perfect. There are, of course, some shortcomings in it, but it is absolutely not necessary to take them into account, since they are insignificant.

The device is perfect for those who want to control the quality of the liquid they use, as well as the water in the pool, aquarium, and so on. People speak positively about the good work of the tester. After all, there is no need to press too many buttons and carry out many actions, but just press one button, lower the device into the water and see the exact value.

When there is a need to quickly check drinking water, this device will come to the rescue. Unlike the previous model, this device cannot tell about the quality of the liquid in the pool, but it copes with its main task brilliantly.

Such a tester will be of interest to both adults and children, because it is made in the form of strips. They work on the principle of focus for children, where litmus sticks are required. When the tester is lowered into the water, it turns into a certain color, by which you can understand the state of the liquid.

The tester is designed to detect metals, although it even copes with bacteria and pesticides. The universal product is consumed quickly, so people have to regularly spend money on it. Although in fact the cost is not so high - about $ 21.

Buyer opinions

First of all, people who have used the tester at least once note the convenience and quick results. Unlike other similar products, these strips show the result in just 20-30 seconds, which really pleasantly surprises consumers.

Users claim that thanks to the device they constantly check the condition of their filters and their operation. This makes it possible to always drink only clean water and be completely protected from all sorts of ailments that a person may have due to the use of poor-quality water.

HM Digital TDS-4 Pocket Size TDS

A simple and accurate portable tester, which costs up to sixteen dollars, became a real bestseller literally a day after the release. Despite the fact that most often people pay attention to devices of well-known brands (for example, Xiaomi), the tester from the Digital brand conquered customers with its quality of work and affordable price.

His device is capable of measuring levels up to 9990 PPM, since this indicator is already huge in order to recognize low-quality liquid.

What users say

This device, which can be easily put in your pocket and taken with you on trips and hikes, receives positive reviews all the time. It, like both previous models, is easy to use, has an affordable price and does its job perfectly.

People get a tester for the purpose of testing drinking water, although in fact it does a good job with the liquid in the aquarium. Owners of small fish do not want their pets to feel bad, so they are very happy with such an excellent device that makes it possible to enjoy life.

Other models

In addition to those listed above, there are several other good models:

1. Digital Aid Best Water Quality. The device for $ 16 is distinguished by a maximum 9990 PPM, high performance and a chic shape of the device. In addition, the tester not only determines the new result as accurately as possible, but also remembers several previous ones, which allows you to compare indicators.
2. HM Digital TDS-EZ Water Quality TDS Tester. Among the best handheld devices, one cannot fail to note the model, the cost of which is $ 13. Far from the most budget device has been on the market for a long time, so buyers can be sure of its quality. The device boasts a good PPM range (0-9990), which allows us to speak only positively about it.
3. ZeroWater ZT-2 Electronic Water Tester. The $11 device comes in handy in cases where the owner of the filter has forgotten when it needs to be replaced. The measurement range (0-999 PPM) is enough to see the quality of drinking water. The tester works quite well, but it is not intended for daily use.

All of them are also popular and have a huge number of positive reviews. The only problem is that they can not be purchased in every city. Although the quality of their work is really high.

Impurities of various origins significantly affect the quality of drinking water. These include salts, metals, soluble organic substances. The smell and taste of water depend on these substances. In addition, many of them can harm human or animal health, lead to malfunctions household appliances. To determine how dangerous the water is to use, specialized instruments are used.

Why do you need a device that determines the quality of water

TDS meters are electronic water quality meters. The abbreviation "TDS" in their name means "Total Dissolved Solids" - "the total number of dissolved impurities." In Russian, this is usually called "general mineralization".

Such devices are used in cases where it is necessary to quickly determine the quality of waste, tap or natural water. The devices are often used when starting up and testing wastewater treatment plants. They accurately measure the concentration of impurities in a liquid in seconds.

In everyday life, small filter systems are usually responsible for the purity of drinking water. However, they cannot guarantee high water quality. After all, cheap filters are quickly filled with suspension, after which they cease to cope with the load.

The water may suddenly smell like sewage, become greenish in color, or taste like rotten eggs. Such a decrease in the quality of the liquid is a consequence of the dissolution of foreign substances, natural or artificial, in the water. A water quality control device will help you quickly determine the cause of the problem.

Besides, tap water can negatively affect human health, even if it looks clean. For example, hard water damages teeth. To avoid such an effect on the body, it is necessary to regularly check the quality of the liquid.

Operating principle

Ordinary drinking water is a good conductor of electricity. This is the basis for the operation of the water quality assessment device. The device creates electric field inside the liquid, measures the magnitude of the current, and from it determines the presence and concentration of impurities.

The received data is displayed on the device display. The number displayed on it indicates the number of impurity molecules per million water molecules (abbreviated as ppm). In the usual system of measurement, this is the weight of impurities in milligrams per liter of liquid.

The result should not be zero, since the complete absence of salts and minerals can also be harmful to health. This number will be obtained if the device is lowered into distilled water or machine oil. It is best if the impurity content does not exceed 50 ppm. At the same time, a value of up to 350 ppm is considered relatively safe.

TOP-5 water quality testers

The tester is a convenient compact device that is easy to use both at home and at industrial facilities. They are inexpensive, but the benefits of their use are endless.

You can choose and purchase a similar device for determining the quality of drinking water at the Kvanta + company.

Xiaomi Mi TDS Pen

The Xiaomi brand has become famous as a manufacturer of smartphones and accessories for them, but now among the products of this brand you can find a lot of home appliances. An excellent example is a water quality control device. Thanks to affordable price This tester is distributed not only in cities, but also in small towns.

The device looks like an electronic thermometer. It has a battery slot on top and two titanium electrodes on the bottom.

The measurement result is presented with an accuracy of an integer value, which is sufficient for most everyday tasks. To avoid errors related to the temperature of the liquid, the tester is equipped with a function to measure the heating of water.

The device is capable of detecting the following substances:

• organic impurities;
• calcium and magnesium salts;
• heavy metals.

This meter is suitable for people who live in areas with high water hardness. In addition, it will cope with water measurements when filling the pool or aquarium.

ZeroWater ZT-2 Electronic Water Tester

The measuring range of this instrument is from 0 to 990 ppm. This is quite enough to measure piped water in an apartment or when filling a pool.

The insufficiently high quality of the materials used is compensated by the accuracy and cheapness. The cost of the device rarely goes beyond 700 rubles.

Water quality analyzer salinometer TDS-3

As can be seen from the name of the device, its main task is to measure the salt content and the total mineralization of water. The device is compact and easy to operate. It is used to assess the quality of water in wells, aquariums, after filters and membrane systems.

The price of this device varies within 500 rubles. You can take it with you on vacation or on a trip. The tester is equipped with a protective case, which is attached to a belt or backpack strap using a special clip.

It is important to remember that the body of the TDS-3 tester is not moisture resistant.

It cannot be immersed in water deeper than allowed. The ingress of liquid into the electronic "stuffing" of the device will lead to a breakdown that cannot be repaired under warranty.

In addition, the meter is sensitive to heat - it should not be left in the scorching sun. Compliance with simple rules of use and storage will significantly extend the life of the tester. Just remember to change the batteries regularly.

Specifications

Calibration of the TDS water quality tester is carried out in the factory using a salt solution. The measurement accuracy does not allow the device to deviate from the truth by more than 2%. Temperature estimation systems allow the device to work with liquid heated up to 80ºС. The total weight of the device is 67 g with dimensions of 15.5x3.1x2.3 cm. Alkaline batteries are used for power. Their characteristics are presented in the table below.

Instruction

Measurements with the TDS-3 instrument are carried out in 3 simple steps:

1. A sample of liquid is taken into a clean beaker.
2. The protective cap is removed from the device, the “ON” button on the device is pressed.
3. To measure, it is necessary to hold down the "hold" key and lower the probes of the device into the liquid. The device is kept lowered into the water for 10 seconds, after which the readings on the display can be considered correct.

You can determine how safe the measured liquid is on the following scale:

• 50 ppm is ideal water for drinking;
• up to 170 ppm - safe water, has a slight mineralization;
• up to 300 ppm - tap water with increased hardness. Considered conditionally safe;
• up to 400 ppm - raw liquid from the source;
• up to 500 ppm and above - potentially dangerous water for drinking.

conclusions

If you need to quickly measure the concentration of impurities in the water you drink, you should purchase a compact tester. Inexpensive devices that accurately determine the content of salts, metals and organic impurities are well suited for both tap water and wastewater.

The use of high-quality water favorably affects the well-being of a person. That is why it is so important to control the purity of drinking water.

Today I will try to take on the role of our valiant Rospotrebnadzor and check the quality of the water we drink. More precisely, I will tell you about a device that is available to everyone and which can check the suitability of water for drinking, moreover, quite qualitatively and at home.

What for?

We are talking about Xiaomi TDS. The device is curious from several sides at once. Firstly, this is a gadget from Xiaomi, which in itself is interesting for any techno-geek in our country, and not only in our country.

Secondly, each of us, for sure, at least once in his life, but wondered about the quality of the water that he uses for food. Most of us do not drink tap water and rightly so. We do not live in Italy, but in Russia, with communication systems that have already served their purpose. Hence the quality of the water that flows through our pipes. But this is only one side. Some citizens like to travel, find springs and collect water for drinking or pots for cooking. The point, of course, is good, but it will not be superfluous to check the sanitary condition of such water.

And thirdly, the gadget is inexpensive, and in view of the approaching favorite holidays of all of us on February 23 and March 8, it is perfect as a useful gift for a loved one.

Xiaomi TDS price on the official website is 35 Chinese yuan or $5.30, or about 400 rubles. I bought a gadget in one large Chinese online store for $7.25. At first I wanted to post a link to the product, but then I changed my mind. The parcel went to me for two months, so I definitely will not recommend such a store. In private, please.

Theory is important for everyone!

In general, Xiaomi TDS is called so for a reason. The name stands for Total Dissolved Solids and should be understood as the total amount of dissolved (in water) solids. Accordingly, the gadget measures this parameter.

The unit of measure is usually the ratio of milligrams of various solids dissolved in one liter of water (mg/l).

In the case of our device, the ppm unit is used. It stands for the number of particles per million particles of water or in English parts per million (ppm). For ease of understanding, these two units of measurement can be equated. They are really very close to each other.

Functional

Xiaomi TDS is a tiny and stylish device that allows you to determine the exact amount of solids dissolved in one liter of water. Of course, the device may be wrong, but in most cases the error will not exceed two percent of the result. This is exactly what the manufacturer says.

The gadget can recognize the presence of the following substances in water: calcium, magnesium, zinc, chromium, lead, copper, heavy metal ions, ammonium acetate, various salts, organic compounds, and so on. All these substances in a certain amount can be harmful to our body.

As a reminder, there is a special scale right on the packaging from under the device, which can be used as a guide when measuring the purity of water.

• 0 - 50 - crystal clear water (after deionization, microfiltration, distillation, etc.)
• 50 - 100 - pure water (after carbon filtration, from mountain springs)
• 101 - 300 - ordinary, heavy water
• 301 - 600 - high content of various solids, as a rule, drinking such water is already unpleasant
• 601 - 1000 - critical solids content - bad taste
• 1000 and above - unsuitable for drinking water

Unfortunately, on the box and in the tiny instructions, all the inscriptions are only on Chinese. It is understandable, because the goods are sold exclusively in China, and it is no secret to anyone that in large cities there is a big problem with the environment. First of all, this concerns the purity of air and drinking water.

I translated the above scale using a Google translator and a metric developed by the US Environmental Protection Agency (EPA).

It is very easy to use it. We pressed the button, the value of 0 ppm lit up on the small LCD screen, lowered it into the water, waited 5-10 seconds and that's it. While the device is in the water, it will show its current state, taken out - the value has fallen. As you can see, everything is very accessible.

I tested several types of water that I found at home. And that's what happened.

• drinking water from an artesian well, purified, packaged in 19 liter bottles - 78 ppm
• Aqua Minerale non-carbonated - 60ppm
• the same, but already boiled water - 86 ppm (the kettle was not pre-washed, perhaps additional salts accumulated from there)

• tap water - 322 ppm
• orange juice - 1030 ppm

But the most interesting indicator was given by melt water - 12 ppm. I scooped snow for her into a glass right in the yard. So think after that, what kind of water you need to use.

Specifications and design

The gadget is powered by two replaceable AG13 button batteries. I'm glad they are already included. The manufacturer was not greedy.

Batteries are hidden at one end of the "handle". In the middle is a small monochrome display, and next to it is a single "TDS" button.

At the bottom end there are sensors covered with a transparent matte cap.

A large contact is responsible for measuring the temperature and calibrating it (not shown), and two smaller "antennae" made of titanium take on the responsibility of measuring solids dissolved in water.

The device is dressed in the form factor of an ordinary stationery marker. The case is entirely plastic, glossy, most likely, over time it will become covered with scratches and become like a devil with horns. But it's beautiful! And it looks great in the box. What else is needed?

• model XMTDS01YM
• operating temperatures: 0 - 80 degrees
• dimensions: 150 x 16 x 16 mm
• weight 28 g

Of course, the gadget is resistant to water ingress according to the IPX6 standard. From here it does not matter how deep you dip your "pen" into the liquid. The only thing I have not tried to completely lower the device under water. I don't think anything will happen, but I didn't.

Outcome

Overview Xiaomi tester TDS the purity of drinking water turned out to be quite short. On the other hand, what else can be said? A simple, useful little thing in the household, which, let's be honest, will be lying around in one of the drawers in your kitchen. I hope I am wrong and will use this device myself from time to time.

At the end useful information. Perhaps someone does not know. The Department of Rospotrebnadzor is responsible for the quality and safety of drinking water. It is the employees of this department that should conduct appropriate checks in the territory they control. Do not be lazy and go to the website of the local representative office to ask how things are with drinking water in your area. To do this, put the code of your region before the page name and look for the information you need in the site search. For example, 77.rospotrebnadzor.ru is the page of the Moscow Office.
