The 123 ORP Sensor is a high resolution, non-corrosive sealed electrode. For accurate measurement and control, this Chemtrol sensor utilizes a platinum band on their ORP sensor.

The ORP sensor samples water from the filtration system and sends signals to the controller indicating the oxidation-reduction potential (redox) of the water. ORP is an actual measure of the sanitizer activity (chlorine, bromine, ozone, etc.) and bacteriological water quality rather than an expression of chemical residual levels. The minimum standard is 650mv set by health departments.

ORP sensors are engineered to provide the highest performance and longest possible functional service life. If properly cleaned sensors provide unstable readings or require excessive calibration, the pair of sensors should be replaced. For optimum controller performance, it is recommended to replace with the original manufacturers sensors. If properly maintained, normal life expectancy is 2-3 years, although many operators replace annually.


Features:
  • Comes with a standard 10' coaxial cable with BNC connectors
  • One-year manufacturer limited warranty.

Cleaning:
The sensors must be clean and free from oil, chemical deposits, and contamination to function properly. After saturation in pool or spa water, the sensors may need to be cleaned on a weekly or monthly basis depending on bather load and other facility-specific characteristics. Slow response, increased need to calibrate pH, and inconsistent readings are indications that the sensors are in need of cleaning.

To clean the sensors, disconnect from the controller and carefully remove them from the flow cell. Clean the reference junction (the white Teflon ring at the bottom of sensor body) with a soft toothbrush and regular tooth paste. A household liquid dishwashing detergent may also be used to remove any oil. Rinse with fresh water, replace Teflon thread-seal tape, and reinstall sensors. Hand tighten only. Never allow a ORP sensor to dry completely. Drying will damage the reference junction and void the sensor warranty.
