This detector detects generally used refrigerant gases (R22, R123, R134a, R404, R407, R410 etc) in the range 0-1000ppm. Each dectector is calibrated to a specific gas type. It has a configurable analog output, 4-20 mA; 0-20 mA; 0-5 V; 0-10 V.There is also a volt free relay which can be user programmed to operate anywhere within the sensor range. The unit is powered from 24 VDC.

Refrigerant Gas-Plant room, Office Gas Detection

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 gas leaks.. R22; R123; R134, R407; R410; Ammonia, Carbon Dioxide; Propane

MEETS THE REQUIREMENTS OF  AS 1677.1 & 2

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.

Food Processing-Chlorine, Sulphur Dioxide, Oxygen, Carbon Dioxide Gas Detection

Purgative gases such as Chlorine and Sulphur Dioxide present OHS requirements for workspace monitoring. Ammonia is often used as a refrigerant gas and can present OHS requirements for monitoring. Carbon Dioxide used in food packaging and stored on site needs to be monitored.

Air Conditioning-Refrigerant Gas and Carbon Dioxide Gas Detection in 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.

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.
