  • Page 7: Functional Description

    Introduction Functional description Brief description of the function Parameter Value Measured variable Peracetic acid (C Measuring range: 0.2 ... 20 mg/l pH-range: 5.5 ... 8.0 The sensor is a diaphragm-covered, amperometric three-electrode sensor. The sensor can be used to determine the concentration of peracetic acid in water. A platinum cathode acts as a working electrode and a silver halide-coated anode acts as a counter and reference electrode The peracetic acid contained in the sample water diffuses through the diaphragm.
