Chemtrol has introduced a new line of PPM sensors for direct measurement of FREE CHLORINE in water in parts per million (ppm) or milligrams per liter (mg/l). Unlike other chlorine sensors on the market, these sensors are very precise and so reliable that they are covered by a 2-year warranty. They are easy to install and practically maintenance free.

The PPM sensor can be used alone or in combination with an ORP sensor to give the operator complete control of water quality. For better water management results, it is recommended to use ORP control of chlorine oxidizing activity and PPM monitoring of free chlorine. Alternatively, PPM control can be used for control of the sanitizer and ORP control for a non-chlorine oxidizer.


  • Free Chlorine measurement (same as DPD #1) in ppm or mg/l including: free chlorine (HOCl and OCL-) and chlorinated isocyanurates, if present
  • pH Range of 5.5 to 9.5 (0.1 to 10 ppm)
  • Temperature Range of 5 to 50%C (40 to 120%F)
  • Cyanuric Acid compatible
  • Pressure Range up to 3 bars (45 psi)
  • PVC Body with 1 inch MPT fitting
  • Replaceable Membrane
  • Sensor Cell with specially designed probe housing
  • Easy Calibration on startup

Chemtrol free technical support for the PPM Sensors.
