Pure Water Tester PWT

The PWT (pure water tester) is a TDS meter which can be used for simple qualitative analysis of the process water (permeate) of reverse osmosis units or for determining the water quality of pure water filters / mixed bed resins. When you press the power button, the scrolling value will be displayed in ppm for 3 minutes. An increasing value indicates the need to change the membrane or filter and to replace the pure water filter or the mixed bed resin. The PWT can be easily retrofitted to any standard reverse osmosis unit with a 4/6 mm hose connection via the T-connector supplied.
