The GDA 2525 carbon monoxide gas sensor is a 2 wire 4-20 mA Loop Powered device. It has an electrochemical carbon monoxide sensor unit which is temperature compensated. The carbon monoxide sensor element is on a pluggable lead to allow ease of replacement. The carbon monoxide gas sensor comes with user selectable ranges 0-100ppm, 0-150ppm and 0-200ppm. The carbon monoxide 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.

Car Park Gas Detection

The Gas Detection Australia  car park gas detection system comprises of 1-8 GDA 2525 carbon monoxide car park  gas detectors and a control unit type GD2400. 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 (2012) call for variable extraction control and minimum flow rates. The Gas Detection Australia  car park system allows VSD control  that will meet all the requirements of the  car park gas detection standard . The car park carbon monoxide sensors (GDA 2525) are designed to be unobtrusive , simple to instal and calibrate . All systems manufactured by Gas Detection Australia  are built , programmed and tested in our factory prior to delivery and will only require wiring and connecting .

MEETS ALL THE REQUIREMENTS OF AS1668.2-2012

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.

Perimeter-Ammonia Gas Detection

The robust 2500 series sensor s along with Gas Detection Australia  range of controllers can be used to monitor low level gas emissions from plants using or manufacturing gases such as Ammonia

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.

Generator Rooms-Flammable Gas Detection

A range of devices from single point go / no go detectors such as the GDA 290 through to sophisticated IEC Ex type gas detectors / gas sensors can be used for detection of Natural gas / Propane/ Butane and various other mixtures.

Air Conditioning- Gas Detection for Offices and Classrooms

Air conditioning gas detection systems  are used in a number of ways. In air conditioning plant rooms  Gas Detection Australia  has  gas sensors and gas detectors  for Ammonia , Propane, CO2 and  R134a, R123, R125, R404, R407c  R410a etc. In enclosed laboratories classrooms and workspaces. The Gas Detection Australia  range of flush mounted Air Conditioning gas sensors for Carbon Dioxide GDA 4360 are used by the HVAC industry  to control fresh air input into rooms and modulate supply. In the case of VRF systems needing room air conditioning gas detection  HVAC industry  uses the flush mounted GDA 3160 which are unobtrusive and used to detect low  levels of R134a, R123, R404, R407c, R410 etc.
