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.
