Sensorex, PSG200C, Potentiostatic Chlorine and Ozone Sensor, 1m Cable, Tinned Leads
Features:
- Easy to Clean and Replace
- Economical
- No Maintenance
- Stable Zero
This sensor is made for the economical measurement of Free Chlorine, Chlorine Dioxide, and Dissolved. Ozone in water is primarily designed for OEM customers. Unlike other premium amperometric FCL and CLD sensors using membranes, fill solutions, and drive circuits, this potentiostatic method (also "amperometric") requires an OEM device to drive and measure a constant potential, made through 2 metal electrodes and a reference electrode. The current running through the cell consumes Chlorine or Ozone, and so must be rene-wed through a constant liquid flow. In the potentiostatic method, the electrode's potential is electronically controlled in relation to the liquid, providing a linear relationship between current/concentration and a very stable zero value in the absence of chlorine or ozone. The sensor is easy to clean and replace. At pH values above pH8, a separate Sensorex pH sensor used in conjunction with these sensors is recommended for pH compensation (more accurate).
