ChemTrol CH230 ORP Digital Controller With Sensor

The CHEMTROL® 230 ORP Controller is a simple, easy to use controller designed to monitor and maintain the Oxidation-Reduction Potential (ORP or Redox) of neutral-type sanitizers, such as bromine or dichlor that do not require pH control. A microprocessor-based digital controller, suitable for high-end residential pools, small commercial pools and spas and light industrial applications.

The bright LCD display shows ORP readings, calibration adjustments and alarm limits. The five LED lights indicate the operating mode (OFF, Manual or Auto), feed status, out-of-range alarms and overfeed alarms. The front panel controls include setpoint, calibration, low and high alarm limits, safety timer limit and proportional feed adjustment.

Feed control is either ON/OFF or Proportional. The Proportional Feed feature is particularly useful to avoid overfeeding in small bodies of water. It reduces the feed cycle time progressively as the sensor reading gets closer to the set-point.
