Product Overview:

The 9187 SC chlorine dioxide detector uses a selective membrane sensor for online chlorine dioxide measurement, featuring a wide range and low detection limit. It comes with a built-in temperature probe for temperature compensation. It is an online chlorine dioxide analyzer with strong anti-interference resistance, accurate measurement, and low maintenance requirements.

Working Principle:

The electrolyte and permeation membrane separate the electrolytic cell from the water sample, allowing chlorine dioxide to penetrate the membrane; There is a fixed potential difference between the two electrodes of the chlorine dioxide detector/meter, and the current generated is proportional to the concentration of chlorine dioxide;
At the cathode: ClO2 + 4H+ + 5e-→ Cl-+ 2H2O
On the anode: Cl- + Ag→ AgCl + e-
The selective membrane sensor of the 9187 sc chlorine dioxide detector features a temperature probe for temperature compensation.

Instrument Features:

• Wide measurement range

  The 9187 sc chlorine dioxide detector uses a selective membrane sensor to measure chlorine dioxide, with a measurement range of 0.010 - 2 ppm (mg/L).

• Temperature compensation

  The sensor of the 9187SC chlorine dioxide detector comes with a built-in temperature probe and can automatically compensate for temperature.

• Accurate measurements

  Unaffected by chlorine, bromine, hydrogen peroxide, or ozone, reducing measurement errors, and data can be directly used for compliance reporting and process adjustments.

• Minimal maintenance required

  The 9187 SC chlorine dioxide detector is generally calibrated every two months, with electrolyte and membrane replaced every six months, greatly reducing downtime and labor costs.

Application Areas:

The 9187 SC Chlorine Dioxide Detector is suitable for online monitoring of chlorine dioxide concentration in drinking water and industrial water disinfection and sterilization processes.
