KL-139A/B TDS Tester Total Dissolved Solids Monitor

Available from Kelilong Electron Co.Ltd in China

Product Description
TDS stands for Total Dissolved Solids, which refers to the total inorganic salts and organic substances dissolved in water. Its main components include calcium, magnesium, sodium, potassium ions, carbonate, bicarbonate, chloride, sulfate, nitrate ions and so on. A TDS meter is an instrument for measuring total dissolved solids.
The unit of TDS is ppm (mg/L). Its value is converted from conductivity at a proportional coefficient of approximately 0.7. The reference temperature for automatic temperature compensation of a TDS meter is normally 25℃, with a temperature coefficient of 2%/℃.
The KL-139A TDS meter is IP55 waterproof.
The KL-139B TDS meter supports wall-mounted and embedded installation for easy installation, operation and maintenance, and it can be powered by both AC and DC power supplies.
