Model CL223 -Chlorine and Chlorine Dioxide Transmitter
The CL 223 Chlorine and Chlorine Dioxide Transmitter, with the appropriate sensor, measures over the range of 0.01 to 5mg/l or 0.05 to 20mg/l. The basic transmitter has a 115 VAC power supply, linear isolated current output and one alarm.
- Measures free chlorine and chlorine dioxide including pH or ORP
- 96x96mm panel mount enclosure takes up less space
- pH compensation for free chlorine

- Measuring Range CL 140: 0.05 to 20mg/l
The CL 140 Chlorine Sensor is an amperometric sensor having a gold cathode and silver/silver chloride anode with a rugged PTFE membrane. When the sensor is immersed in chlorinated water, chlorine diffuses through the PTFE membrane. Chlorine molecules are reduce at the gold cathode and silver oxidized to silver chloride at the anode. The resulting current is a direct measurement of the concentration of free chlorine in the process. CL 240 Chlorine Dioxide Sensor works by the same principles.
