Principle
Free chlorine measurement by amperometric method with a diaphragm cell of 2 electrodes; wasted sample.
The probe includes a CTN sensor for the temperature compensation.

Mounting / Recommendations
The measuring at a constant flow rate requires the use of a specific cell (see data sheet 193-95).
The complete assembly optimizes the operations.

The sample may not content surfactants and the pH must be lower than 7.4

Range:
0.5 to 200 ppm (free chlorine)
Measuring signal depends of pH; regulation of pH is necessary.

Operating pH range: From 4 to 7.4 and regulated
Pressure limit: 1 bar as a maximum
Temperature limits: From 1 to 45°C
Flow rate limits: From 30 to 40 L/h (see the data sheet 193-95)
Power supply: 12 ... 30 V DC, [Rmax = (U-7,5) / 20 kOhm]
Materials: PVC-U
Dimensions: Diam.25 mm, length 225 mm
