Chlorine dioxide sensors

sonde de dioxyde de chlore

Chlorine dioxide sensors : CAA2540 – 41
4-20 mA / 0 – 2 and 0 – 10 ppm

CAA2540 and CAA2541 sensors are used to measure chlorine dioxide (ClO2) in drinking water, industrial process or water of similar quality.

Advantages:

  • Amperometric measurement
  • Continuous accurate and reliable analysis
  • Fast execution

Chlorine dioxide sensors : CAA2559 – 71
4-20 mA / 1 ppm

CAA2559 for drinking water and CAA2571 for hot sanitary water are used to measure chlorine dioxide in drinking water, sanitary hot water or in other process where chlorine dioxide measurement must be controlled.

Advantages:

  • Amperometric measurement
  • Continuous accurate and reliable analysis
  • Fast execution
  • Pressure measurement – up to 8 bars
  • High temperature of 50 to 70 °C

Applications
