Chlorine dioxide is a neutral chlorine compound. It is very different from elementary chlorine, both in its chemical structure (ClO2) and in its behaviour. One of the most important qualities of chlorine dioxide is its high-water solubility, especially in cold water. Chlorine dioxide does not hydrolyse when it enters water; it remains a dissolved gas in solution. Chlorine dioxide is approximately 10 times more soluble in water than chlorine. It is not affected by pH and has an excellent residual effect remaining active for hours to days.

The Sensorex CLD series (chlorine dioxide sensors) feature amperometric measurement technology.
With a direct ModBUS RS485 output, the CLD sensors can be used with any instrument accepting ModBUS input or connected directly to a PLC or SCADA.
Choose the CLD502 for 0-2ppm, CLD505 for 0-5ppm and CLD510 for 0-10ppm of chlorine dioxide.

• Industrial wastewater
• Cooling water
• Bottle Rinsing
• Irrigation water in agriculture

Membrane cap and fill solution are easily replaceable to maximize sensor life.
Sensors should be used in new installations with the Sensorex flow cell.
An optional flow meter (FM001) is available to ensure regulated flow between 0.2 to 0.6 gpm for optimum sensor accuracy.
