  • Power Supply 12 or 24 VDC
  • Digital internal processor.

Measurement Range

  • 0.5PPM-2PPM  Resolution in PPM 0.1PPM

Temperature Compensation

  • Automatic by integral temperature sensor

Bromine Sensor Functionality

  • H2T0974 is a specifically designed sensor for measurement of hypobromous acid in water.


  • Do not come in physical contact with the membrane or the electrode tip that contacts the membrane
  • Do not allow a no flow situation for longer than 4 days continuously after polarization
  • Do not allow exposure to ground current higher than 3 mV for an extended period of time
  • Do not expose to pressure higher than 8 PSI as it will rupture the membrane
  • Do not expose to temperatures below 40 Degrees F or higher than 115 degrees F
  • Do not allow air to be within the membrane cap when filled with electrolyte and in use
  • Do not expose sensor to other Halogens such as Flouride, Chlorine or Ozone or Iodine as it causes an interference offset in the reading
  • Do not allow flow past the probe to be less than 10GPH or higher than 15 GPH as this will damage the probe


  • Can be effectively calibrated using a DPD-1( Free Chlorine)  method with a multiplication of reading by 2.25 to show the concentration of Bromine in Mg/l
