Water treatment (for water equivalent to drinkable quality) at a constant pH.

Measured parameter: Free chlorine
Chlorination additives: Inorganic compounds, such as NaOCl - Ca(OCl)₂ - gaseous chlorine, chlorine produced by electrolysis
Caution: Surfactants not tolerated
Output signal: 4 ... 20mA
Operating temperature 1 to 45 °C
Automatic temperature compensation
Operating pressure 1 bar max. (No vibrations, no pulsating flow)
Flow rate About 30 l/h
pH operating range: Constant between 6 and 8 pH, pH value must be constant
Interferences: Strong incidence of ClO₂ and O₃ on measuring signal; Chlorine produced by electrolysis with a non-diaphragm cell may cause damages.
Zero adjustment: Not necessary (from factory)
Slope calibration:  Only 1 point with BAMOPHAR 194 according to directive DPD-1
