TDS Sensor Online
We Know That TDS Sensor / Online TDS Sensor / TDS cell Online used to test Water Quality.
What is TDS?

Hence The PPM (Particle per Million) TDS value (Total Dissolved Solids) gives; the sum of total dissolved solids in water. While these solids may be salts, minerals, and metals. Mostly Sodium and magnesium salt fond dissolved. TDS measred in PPM.
While The conductivity of the water or any solid / liquid; measured indicates ions are in the water, the better it conducts electricity. Hence TDS meters typically quantify this conductivity in micro siemens UCM or MCM. The latter stands for parts per million; i.e. the number of solid particles per one million water mixture particles. Hence A value of 40 ppm means that from one million particles there are 40 dissolved ions and the rest (= 999 960) are water molecules.

What does it mean about the water quality?
Hence DM water with a ppm value of zero; is automatically free from any pesticides and drug residues, is far from it. While All the TDS meter measures are merely the number of ions in the water. Most of the pesticides, hormone-disturbing substances; and drug residues are usually no ions!
Hence In short: water with a low ppm value is virtually free from salts and minerals; but can hide a large cocktail of non-ionic chemicals in itself. While The result of a TDS meter is therefore not very meaningful with regard to the actual water quality. While Other analytical methods or a water analysis by a reputable laboratory; may be better suited to find out about the actual water quality.

Observation as analyst
Hence if you want to check the functionality of an osmosis system; the mere TDS values are not suitable as an indicator of the water quality. Hence extensive and detailed water analyzes are often very expensive and only reflect a snapshot; While they are only advisable if the drinking water is to be tested for individual substances. So It often makes more sense to invest in a high-quality water filter right away. This way you have more security with your daily drinking water consumption in the long term. While, it is essential to pay attention to appropriate assessments and long-term studies; Because the label “filters pesticides” can also mean; Hence with an inferior filter, that only 5% of the pesticides are removed; While the retention rate drops rapidly after a short time.
