HM Digital TDS-EZ Meter Water Quality Tester ppm

A Digital TDS Meter indicates the amount of Total Dissolved Solids (TDS) in a solution. Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution then converts that figure to an estimated TDS reading.

A Digital TDS tester that's ideal for all water purification applications, wastewater regulation, aqua culture, hydroponics, and colloidal silver. Perfect for both consumer or commercial use. Carry one in your pocket at all times!
