The GDA 2626 Ammonia gas sensor is a further enhancement of the GDA 2526 Ammonia gas sensor that allows AC and DC operation. It has an electrochemical gas sensing unit which is temperature compensated and easily replaceable.

Designed, manufactured and supported locally in Australia.

The gas sensor element is on a pluggable lead to allow ease of replacement. The gas sensor electronics are housed in a robust ABS sun tolerant plastic enclosure rated IP65; the sensor head and its electronics are housed in a metal enclosure giving it excellent RFI and EMC compatibility. The sensor head is fitted with a splash proof cover giving an IP62 rating. Provides the option of 4-20 mA, 0-10 V, and 0-5 V operation. The additional voltage o/p can be used on BMS systems that use voltage inputs as opposed to current input

  • 0-100 ppm Range (Other ranges on request)
  • 4-20 mA, 0-5 V or 0-10 V o/p
  • Low cost replaceable gas sensor element
  • Easy to install
  • Easy to calibrate (only gas and multimeter required)
  • ABS sun tolerant IP66 housing (sensor element IP62)
  • Australian Factory Certificate of Calibration

Made in Australia and Supported in Australia

Cold Rooms

The use of Carbon Dioxide gas detectors / gas sensors or Nitrogen gas detectors / gas sensors in cold rooms can result in asphyxiation if the levels get too high . Work place health and safety places a requirement for monitoring these gases

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.
