    A bright LCD display shows pH readings, calibration adjustments and alarm limits. The five LED lights indicate the operating modes (OFF, Manual or Auto), feed status, out-of-range alarms and overfeed alarms. The front panel controls include set point, 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 approaches the set point.

    All CHEMTROL controllers are user-friendly, reliable and easy to install and operate. Every unit is supplied with a comprehensive operation manual and a FIVE-YEAR electronics warranty.
