Santa Barbara Control Systems | Chemtrol 240 PH Controller with Sensor | CH240
The CHEMTROL® 240 pH Digital Controller automatically maintains both the sanitizer pH (oxidation-reduction potential or Redox) level.
All operating functions are clearly labeled and accessible from the front panel, with many safety and easy-reset features not found on other controllers:
  • pH calibration from 4 to 10,
  • pH setpoint from 4 to 10,
  • feed modes: off, manual, automatic,
  • proportional control bandwidth from 0 to 100% of the setpoint,
  • pH high and low alarms from 4 to 10,
  • overfeed safety timer from 0 to 99 minutes.
To select a function, simply press pH and then the desired function.  The display shows the current function value.  Use the UP or DOWN arrows to adjust to the desired value.
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.

is a microprocessor-based digital controller designed to maintain the pH level in water treatment applications.

  • Adjustable Alarms
  • Proportional Feed
  • Overfeed Safety Timer

The bright LCD display shows pH 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 setpoint.

Installation of the CHEMTROL® 240 is as easy as 1-2-3.

CONTROLLER - Connect the controller to the 110 or 240V output of the Timer in parallel to the recirculation pump.  This will prevent accidental feeding of chemicals when the pump is not running. Make sure to follow the electrical code.
SENSOR - Install the pH sensor on the recirculation line or on the optional bypass line.  The sensor can be mounted directly on the main recirculation line with a 2" PVC tee, as shown on the schematic.  For recirculation lines over 2" in diameter lines, the sensor should be mounted on a 1/2" bypass line.
CHEMICAL FEEDER - Connect the chemical feeder to the 110 or 240V controller output, according to the manufacturer's instructions, making sure to inject the chemicals downstream of the sensor. For a bromine or chlorine erosion feeder, install a corrosion-resistant solenoid valve on the intake line of the feeder. The controller is compatible with most ozonators and electrolytic generators.
