Best aqua testers to measure water in 2024

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

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

1. Redox potential of a liquid. This figure should be in the range of 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. The 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. Excess of these substances damages the kidneys. Their low content is also not useful - in this case, the body will experience a deficiency of essential salts and minerals.
5. The norm of the indicator of the surface tension of water is 73 dynes / cm. This water is easy for the body to absorb.
6. In addition to the above, drinking water should not contain heavy metals, nitrates, nitrites, chlorine and organic compounds of any kind.

What is an aqua tester for?

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

This device can be simple, pocket-sized, or a complete set for complex liquid analysis. If you have a pool in a country house or in the country, you will need a special set of testers to check the pool water for the content of chlorine, bromine, 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 higher this indicator, the more water pollution ). The norm is from 100 to 300 PPM. The measurement result is shown on the display.

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

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

Types of aqua testers

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

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

Multiparameter. Several types of analysis are performed:

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

Also, testers differ in the type of analyzed water:

• tap,
• ground,
• from an artificial reservoir,
• 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 water).

Criteria for choosing an aquester

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

If you suspect that the water is hard, it is best to purchase a TDS-3 Salt Meter. 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 a liquid by 11 of the most important parameters - a multi-parameter tester, for example, U-50. Any model from this series is distinguished by high efficiency, convenient operation (built-in control unit) and accessible instructions. In addition, multivariable water testers of this series are able to memorize the results of the analysis, which are then easily entered into a personal computer and thus monitor the state of water quality, monitor possible changes in its composition.

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

A special oximeter is designed to detect and calculate the concentration of oxygen (O2) in water. For home use, it is best to purchase the Extech DO600 + and the AZ8401 model. Both instruments are a gas analyzer capable of conducting research in an open well of any depth and in a closed sealed 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 analysis results and subsequently compare them with each other. The number of reports that can be saved is 25. The second option, AZ8401, is designed to detect and calculate the amount of oxygen not only in ordinary drinking water, but also in any body of water, including natural (for example, in order to determine whether a given reservoir is suitable for fishing, or breeding in it fish). It should be added that O2 measurements are best done regularly, since the oxygen concentration is subject to constant changes, depending on weather conditions.

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