May 2, 2017 at 13:51Xiaomi TDS Pen: measure the level of mineralization of water
Today, we’ll talk about one of those Xiaomi gadgets that is not synchronized with anything - the water tester.
Why it is useful
Mineralization of water is one of the criteria of both water quality and classification. The study evaluates the presence of solids. In the Western tradition, the term " Total dissolved solids " is used, the abbreviation of which gave the name to the Xiaomi gadget (as well as many others). Depending on the level (degree) of mineralization, it is customary to distinguish several types of water.
At the same time, the low level of mineralization of water is bad, as well as high. In some notesIt is noted that the systematic use of water with a low level of mineralization can provoke long-term diseases of the heart, bones, etc.
Why it is useless
In Russia, the quality of drinking water, including bottled , is regulated by the requirements of SanPiN .
An attentive reader will immediately say that mineralization is only “one of” the parameters that affect the quality of the liquid and therefore close attention to particular will not help to avoid a poor-quality product in general. In general, it is.
It is also worth noting the "spread" in numbers. Here, for example, are the norms for pre-packaged waters:
You will find the same numbers without fail on any packaged water.
And, I can say for sure that the handle will fall into this range! Running even a little further, in terms of mineralization, the water from the tap will be about the same level as that packaged in bottles. And running a little further ahead: Aqua Mineral had the lowest level of mineralization ( according to the handle ).
Units of measure . The indicator is measured in mg / l or parts per million (ppm). 1 mg / L = 1 ppm.
Xiaomi TDS Pen
Xiaomi does everything . Therefore, the presence of this pen in the assortment, although it was surprising at the time, was not very impressive after the screwdriver, toothbrush, and so on and so forth.
We bought our TDS Pen on Ali, although the Market now caught about the same amount of money .
The gadget comes in a rectangular white box. She becomes mint on the way.
On both sides of the lid: under the one that is decorated with the Mi logo, there are batteries.
On the other hand, the tracker itself. These are three "antennae", two of which are of the same length and thickness, one is a little thicker, but much smaller.
There is only one button on the case that activates the device, after which the handle must be lowered into the water with the working side. Data is displayed instantly. After that, just shake the pen once, like a thermometer, and it will reset the readings.
As with weights(and there were questions), although the data is reproduced with enviable constancy, it seems impossible to confirm or refute the accuracy of the sensor at home, nevertheless, it is probably not just a “set of numbers”.
Measurement with an interval in time:
For those who want to make sure that our drinking bottled water complies with SanPiN, we give a few more examples. But pay attention to the “Aqua Mineral” and the table, a screenshot of which we gave above. Not enough ...
We would not begin to draw any long-term conclusions from this and attack the manufacturers, since the level of mineralization, as they said, is only one of the quality parameters. Moreover, if you believe the same tracker and the same numbers, then the water from the tap is no different from what is bottled.
Hmm ...
In general, take care!
