Product Description
TDS is the abbreviation of Total Dissolved Solids, which stands for the total amount of inorganic salts and organic matter dissolved in water. Its main components contain calcium, magnesium, sodium, potassium ions, carbonate ions, bicarbonate ions, chloride ions, sulfate ions, nitrate ions, etc. Therefore, a TDS meter is a tester for measuring total dissolved solids.
The unit of TDS is ppm (mg/L). Its numerical value is converted from conductivity with a proportional coefficient of about 0.7. The reference temperature for automatic temperature compensation of TDS meters is usually 25℃, with a temperature coefficient of 2% per ℃.
The KL-139 series pen testers feature reliable measurement results, simple and quick operation. This pen-style TDS meter is convenient for handheld testing and equipped with an LCD screen to display readings clearly.
