This TDS (Total Dissolved Solids) Demonstration Device, also known as a Precipitator, Electrolyser or TDS Indicator, is used to show a visible difference between unfiltered tap water and filtered/ purified water samples. The unit has been used once and worked just fine. The precipitator comes with a case, power cord and US wall outlet adapter, and a spare set of iron rods.
