Concentration measurement of free chlorine or chlorine dioxide, hot sanitary water
and drinkable water.
Caution: The pH must be constant for free chlorine measurement.

Measured parameter:

• AS ... CL: Free chlorine
• AS ... CD: Chlorine dioxide

Disinfection additives: Inorganic compounds, such as NaOCl, Ca(OCl)₂, gaseous chlorine, chlorine produced by electrolysis
Chlorine dioxide: Chlorite/ Chlorine; Chlorite/ Acid
Measuring system: Semi-open cell with 3 electrodes and electrolyte
Output signal: 4 ... 20 mA
Operating temperature:

• AS2: 1 to 50°C
• AS3: 1 to 70°C

Automatic temperature compensation
Ambient temperature: From 0 to 55 °C
Operating pressure: 8 bar max.
Cleaning system Equipment: RV1 (option)
Flow rate: Flow must be constant

• 15 l/h as a minimum, without RV1 equipment
• 45 l/h up to 90 l/h  with  RV1  equipment

pH operating range:

• AS ... CL: pH must be constant
• AS ... CD: between pH 1 and pH 12

Zero adjustment Not necessary (from factory)
Slope calibration: Only 1 point necessary with BAMOPHAR 194:

• Chlorine: DPD-1
• Chlorine dioxide: DPD-1 (without chlorine)

Interferences:

• AS ... CL: Ozone, chlorine dioxide and chlorite
• AS ... CD: Ozone, chlorine, chlorite, measured with less than 2% of their concentration
