سختی سنج آب مدل TDS-3

Ironically, a TDS meter does not initially measure TDS, which is where much of the confusion arises. TDS meters, also known as TDS testers or indicators, are digital or analog meters that measure the electrical conductivity of water. Based on that conductivity, the meters estimate what the true TDS level might be.

TDS is the abbreviation of total dissolved solids in English, the Chinese translation is total dissolved solids, and the unit of measurement is milligrams per liter (mg/L), which indicates that 1 liter of water contains milligrams of soluble solids.

The concept of TDS is an imported product and is widely used in the field of water treatment in the United States and Taiwan. The TDS value measurement tool is generally a TDS pen. The measurement principle is actually to indirectly reflect the TDS value by measuring the conductivity of water. In a physical sense, the more dissolved substances in the water, the greater the TDS value of the water, the better the conductivity of the water, and the greater the conductivity value.
