Flow Independent Operation


  • Provides internal flow within sensor using magnetic pump
  • Agitates plastic balls that continuously clean the electrodes
  • Long life Brushless DC Motor has 20,000 hour life
chlorine sensor measurement

Measuring Principle
HOCl + H+ + 2e- --> Cl- + H2O


  • Measure the electrons from reduction of HOCl (or HOBr) at the cathode (current)
  • This is the opposite reaction to what happens in a chorine generator
  • The reaction is limited to the species we measure by using a fixed potential
  • For example - we do not want to measure dissolved oxygen.

The Only Self-Cleaning TRO Sensor


  • Provides internal flow within sensor using magnetic pump
  • Agitates plastic balls that continuously clean the electrodes
  • Long life Brushless DC Motor has 20,000 hour life

Multiparameter Measurement


This highly integrated chlorine sensor performs a total of five measurements with only four electrodes and much of the same circuitry; the cost of the sensor is dramatically less than several discrete sensors. This new chlorine sensor platform enables the measurement of five parameters a total of only four electrodes and a temperature sensor.
Commercial Swimming Pools.

Robust pH Sensor


  • Our pH sensor is the only commercially available (non-ISFET) pH sensor that does not require wet storage
  • It is the only pH sensor that can withstand -0.7 bar and 10 bar
  • The sensor wets rapidly and is accurate within 2 minutes
  • The self-cleaning system also keeps the pH sensor clean
