The best water testers for measuring water in 2022

To purify water in everyday life, various purification filters are often used. But in order to make sure that the water is devoid of harmful or excess impurities, it is useful to use a special water tester - this device will help not only test the water for drinking, but also conduct its chemical analysis. Based on the results of such an analysis, showing the level of contamination of the liquid and revealing its composition, you can choose a method of water purification.

Clean drinking water must meet state standards for a number of indicators:

1. The redox potential of a liquid. This indicator should be in the range from 50 to 100 millivolts. Otherwise, the body will spend a lot of resources in the process of restoring the redox potential.
2. The pH should be neutral (mark 7.0). In this case, a slight presence of alkali is permissible, but there should be no oxidation at all.
3. Water hardness should be at an average level. Soft water along with hard water is unacceptable for consumption.
4. The presence of minerals and salts should not exceed the norm. An excess of these substances harms the kidneys. Their low content is also not useful - in this case, the body will experience a deficiency of the necessary salts and minerals.
5. The norm for the surface tension of water is 73 dynes / cm. This water is easy for the body to assimilate.
6. In addition to the above, drinking water should not contain heavy metals, nitrates, nitrites, chlorine and organic compounds of any kind.

Why do you need an aquatester?

Ordinary personal water filters are short-lived - over time, they begin to pass harmful substances and the water acquires an unpleasant odor, most often - hydrogen sulfide, sewage, or chlorine. But not always harmful substances contained in water can be easily detected by smell, then an aquatester comes to the rescue.

This device can be simple, pocket-sized, or a complete kit for complex fluid analysis. If you have a pool in a country house or in the country, you will need a special set of testers that allow you to check the pool water for the content of chlorine, bromine in it, and also to analyze the pH level.

Working principle and characteristics of the water tester

This portable device has a rather narrow functionality - it calculates the number of heavy particles in PPM - ("par per million" - "parts per million") from 0 to 1000, and sometimes up to 10,000 (the larger this indicator, the stronger the water pollution) ). The norm is from 100 to 300 PPM. The measurement result is displayed.

The pocket device is no larger than a thermometer, it is easy to use with a portable filter, especially on the road. It takes only 5 minutes to determine the composition of the water.

A water analysis kit is more complex than a pocket tester. It is a set of reagents that allow, like an indicator, to test water.

Types of aquatester

Monoparametric. The analysis is carried out according to one specific parameter:

• pH level;
• the amount of salts;
• hardness level and so on.

Multiparametric. There are several types of analysis:

• chemical,
• optic,
• electrochemical,
• chromatographic,
• photochemical.

Testers also differ in the type of analyzed water:

• tap water,
• ground,
• from an artificial pond
• technical and waste water.

Aquatesters are also distinguished by the way they are used:

• portable;
• stationary (installed in water pipes, provide an hourly report on the state of the water).

Criteria for choosing an aquatester

Since home filters are not enough to gain firm confidence in the purity and safety of drinking water, it becomes necessary to purchase a tester. What is the best tester to buy? It all depends on what kind of tasks are assigned to this device.

If there are suspicions that the water is hard, it is best to purchase a Salt Meter TDS-3. The device will quickly and accurately calculate the amount of salts in the liquid.

For a comprehensive check of the state of water, it is best to give preference to a universal device that examines the liquid according to the 11 most important parameters - a multi-parameter tester, for example, U-50. Any model from this series is distinguished by high efficiency, convenient control (built-in control unit) and accessible instructions.In addition, multi-parameter water testers of this series are able to memorize the results of the analysis, which can then be easily entered into a personal computer and thus monitor the state of water quality and monitor possible changes in its composition.

If it is necessary to determine the presence of chlorine in water, then for this case it is necessary to purchase a special chlorimeter CL200+. This device has a wide measurement range - from 0.01 to 10 mg / l, which allows you to accurately examine a highly chlorinated liquid. In addition to the main function, the device is able to determine the pH and ORP levels not only in domestic water, but also in any artificial reservoir - an aquarium, pool, boiler, and so on. In addition, the device is economical, since the universal ExTab chemical reagent is used for any analysis. Measurement results are output in digital format.

A special oximeter is designed to detect and calculate the concentration of oxygen (O2) in water. For home use, the Extech DO600+ and AZ8401 models are best. Both devices are a gas analyzer capable of conducting research in an open well of any depth and in a closed hermetic vessel. What is their difference? The first option - Extech DO600 + - is used not only at home, but also in production.

The built-in memory of the device allows you to save the results of the analysis and subsequently compare them with each other. The number of reports that can be saved is 25 pcs.The second option - AZ8401 - is designed to detect and calculate the amount of oxygen not only in ordinary drinking water, but also in any reservoir, including natural (for example, in order to determine whether this reservoir is suitable for fishing, or breeding in it fish). It is worth adding that it is best to measure O2 regularly, since the oxygen concentration is subject to constant changes depending on weather conditions.

To maintain and preserve the health of the body, it is necessary to use and consume only clean water with a normal content of salts and minerals in it. Therefore, an aquatester is one of the most necessary devices in everyday life, because thanks to this compact simple device, you can easily determine the state of drinking water, aquarium water, pool water and even a natural reservoir. Based on the results of analysis or regular research and observation, it is possible to identify the problem and take measures aimed at purifying water and protecting the body from exposure to harmful substances.
