The GDA 2527 Nitrogen Dioxide (NO₂) Gas Sensor is a 2 wire 4-20 mA Loop Powered device with a range of 0-30 ppm Nitrogen Dioxide. It has an electrochemical sensing unit which is temperature compensated and easily replaceable.
Designed, manufactured and supported locally in Australia.
The nitrogen dioxide gas sensor electronics are housed in a robust ABS sun tolerant plastic enclosure. The sensor element is on a pluggable lead allow ease of replacement.
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.

|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 .
