The GDA 2527 Chlorine (Cl₂) gas sensor is a 2 wire 4-20 mA Loop Powered device with a range of 0-10 ppm Chlorine. It has an electrochemical sensing unit which is temperature compensated and easily replaceable.

Designed, manufactured and supported locally in Australia.

The chlorine gas sensor's electronics are housed in a robust ABS sun tolerant plastic enclosure. The sensor element is on a pluggable lead allow ease of replacement.

  • 0-10 ppm Range (Other ranges on request)
  • 4-20 mA o/p (For Voltage Output see the GDA 2600 Series)
  • Low cost replaceable gas sensor element
  • Easy to install
  • Easy to calibrate (only gas and multimeter required)
  • ABS sun tolerant housing
  • Australian Factory Certificate of Calibration

Poisoning: GDA sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.
