The easiest and most direct way to test water quality - TDS Water Environment Monitor

The TDS pen is the most commonly used tool for household water testing. It can determine the local water quality in a simple and intuitive way.

Generally speaking, the TDS value of tap water is tens of hundreds, and the water filtered by the water purifier falls below 10, indicating that the water has been purified.

But... Is the TDS pen applicable to all water purifiers? Is TDS a standard for drinking water quality?

01What is TDS?

TDS is the total amount of solids that can be dissolved in water, and the TDS pen is a device used to measure the total amount of the three solids in water; the higher the TDS value, the more solids are dissolved. The higher the TDS valuetds meter, the more dissolved substances there are. Therefore, the principle of the TDS pen is to measure the conductivity of the water, so as to convert the TDS value of the water. The standard for direct drinking water is a TDS value of less than 50; less than 70 in the EU; less than 50 in the US.

02TDS can be judged on the quality of water good or bad?

How do you know! There are 106 indicators of water quality, and TDS is only one of them. Drinking water must meet standards for turbidity, total bacterial counts, microbial counts, heavy metals and organic concentrations. A TDS water test alone does not determine water quality.

Many people may ask: Isn't TDS useless?

Of course it is!

While TDS is not the only reference value for drinking water, a drop in TDS in purified water is a significant improvement in water quality. Just like a thermometer, which can only tell you if you have a fever, but not whether it's a wind chill, a fever, or a virus, so too can a TDS pen, which is just a device for testing the quality of water, and doesn't know what heavy metals or organic compounds are in your tap water. After all, a complete water quality monitoring device is too expensive, and TDS provides the average person with a quantifiable number at a relatively low cost.

03 "TDS Test Pen

It is the most commonly used water quality testing tool in China, which can be used to determine the local water quality in a simple and intuitive way.

04TDS value also has some inaccurate times?

As a matter of fact, the measurement of TDS value of water purifier is also highly valued,geiger counter radiation detector and many people ignore a lot of external factors in the measurement, which leads to a one-sided view of the high TDS value, and the machine is ineffective.

Factors leading to inaccurate TDS values.

Water Temperature: The TDS pen cannot be used to measure high temperature water.

In general, when the water temperature rises, the calcium and magnesium ions in the water combined with other substances, the conductivity increases, so the TDS value will also become higher, affecting the test results.

2, the serious problem of water pollution: higher concentration of pollution in the water body affects to carry out the measurement system data

In some areas of high TDS value in China, there are even thousands of groundwater,dosimeter vs geiger counter if the raw water quality is seriously polluted, it is recommended that the use of RO reverse osmosis water purifier before joining the preventive measures.

3、Other influencing factors

① Newly installed machines, or new replacement of the air filter element of the machine, the need to carry out water release method of flushing 20-30 minutes before measurement;

② storage of pure water in the storage bucket for too long, will also affect the measurement results;
