3/8'' 800L/h Water Flow, Temperature & TDS Sensor - DWS-MH-02

3-in-1 water flow hall sensor, temperature and TDS meter.

TDS stands for Total Dissolved Solids and is a measure of dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form.

The meter is perfect for systems where quality of water is critical, like food processing equipment.
