CHEMTROL® CH240 pH Controller
pH CONTROL MADE EASY
The CHEMTROL® 240 pH Controller is a simple, easy to use controller designed to monitor and maintain the pH level in water. It is particularly adapted to the neutralization of acidic or alkaline solutions for environmental applications. A microprocessor-based digital controller, suitable in high-end residential pools, small commercial pools and spas and light industrial applications.
STANDARD FEATURES
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.
