The GDA 2627 Nitrogen Dioxide gas sensor is a further enhancement of the GDA 2527 Nitrogen Dioxide 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 carbon monoxide gas sensor electronics are housed in a robust ABS sun tolerant plastic enclosure rated IP56; the sensor head and its electronics are housed in a metal enclosure giving it excellent RFI and EMC compatibility. 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

  • 0-30 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 IP56 housing (sensor element IP22)
  • 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.

Interference: Long lines of voltage signal cables may act as an antenna causing interference and noise leading to false readings and reduced accuracy.

Made in Australia and Supported in Australia

Car Park Gas Monitoring Systems

The Gas Detection Australia car park gas detection system comprises of 1 up to 16 GDA 2525 carbon monoxide car park gas detectors per zone or level. The car park gas concentration signals are sent from the car park gas detector and the highest level from all the car park gas detectors are displayed locally on the control unit.  The latest regulations (AS1668.2-2012) call for variable extraction control and minimum flow rates. Gas Detection Australia car park system's allows variable-speed drive (VSD) control  that will meet this requirement of the australian car park gas detection standards. The car park carbon monoxide sensors (GDA 2525) are designed to be unobtrusive, simple to install and calibrate. All systems manufactured by Gas Detection Australia are built, programed and calibrated in our factory prior to delivery and will only require wiring and connecting .

CALGAS : Calibration Gas

To test and maintain accuracy gas detection systems require regular testing and calibration. GDA can provide you with a complete line of calibration equipment to calibrate all of our gas sensors and detectors. Our calibration gas cylinders all come with N.I.S.T. certification and ISO 17025 approval so you can be confident that you will receive gas with the highest accuracy levels.
