The GDA 3160 is a low profile wall mounted refrigerant detector for use in offices and laboratories where a gas sensor needs to appear non obtrusive. It is designed to fit into a Clipsal double gang GPO wall mount.

Designed, manufactured and supported locally in Australia.

The sensor uses NDIR techniques for detecting a wide range of refrigerant gases and is therefore immune from cross sensitivity to other gases. It has 4-20 mA o/p and interfaces to the full range of GDA control units and will interface to BMS and SCADA. The total protrusion from the wall is 13 mm.

  • Standalone system or 4-20 mA, 0-20 mA, 0-5 V ; 0-10 V + volt free relay
  • Highly selective, Infra red sensor. Not affected by other gases found in offices or laboratories
  • No false alarms due to other gases
  • 1 alarm relay (volt free)
  • 1 x 4-20 mA or 0-20 mA or 0-10 V or 0-5 V o/p
  • 24 VDC operation
  • Flush wall mounted housing. To fit in with office environment
  • Easy to install
  • Calibration required every 3 years with 6 monthly functional tests
  • Australian Factory certificate of Calibration

Made in Australia and Supported in Australia

Flush Mount Gas Sensors

Mounted in wall hole, Non obtrusive, recommended for office rooms, class rooms, laboratories etc. Are designed to fit into a Clipsal double gang GPO wall mount.


Refrigerant Gas: Plant Rooms & Offices

Gas Detection Australia has a range of ultra-low level refrigerant gas leak detection systems specifically developed to prevent the expensive results of refrigerant gas leaks for R22; R123; R134, R407; R410; Ammonia, Carbon Dioxide; Propane and many others.

Meets the requirements of AS/NZS 5149.3:2016

Designed, manufactured and supported locally in Australia.

Air Conditioning Monitoring

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.


Laboratory and Classroom Monitoring

When gas is piped into rooms for experimental purposes such as CO2, CO, or Natural Gas .The Gas Detection Australia range of sensors can be used to detect any leaks that may present a danger to health or explosion.
