The K 100 (W) CM Conductivity transmitter is a sophisticated single-channel instrument for measuring and control of conductive conductivity. Temperature measurement of the measuring media is possible. The instrument is available in a panel mounted housing (K100 CM) and in a wall mounted housing (K 100 W CM). Easy and safe operation by plain text menu guidance. Safety by password function. Linear and non-linear special pure water temperature compensation

Applications: Cooling And Boiler Feed Water, Waste Water Treatment, Process Water
