The GD131 Refrigerant Gas Detector, available from Gas Detection Australia , is an easy-to-use, reliable gas detector that detects the presence of freons, HFCs and CFCs in any area that a leakage of refrigerant gases may occur, such as in air conditioning ducts, machinery plant rooms, refrigeration and IT plant rooms.
The GD131 sensor utilises infra-red technology and is specifically designed to measure low levels of refrigerant gas in the air. Infra-red technology eliminates the inherent problems associated with other methods of refrigerant gas detection, such as semi-conductor and electro-chemical sensors. As a result, the GD131 Refrigerant Gas Detector is immune to poisoning and is a versatile and robust instrument incorporating proven technology.
The GD131 Refrigerant Gas Detector outputs a signal proportional to the concentration of the refrigerant gas detected. This signal is outputted as a 4 to 20mA current. The GD131 Refrigerant Gas Detector can therefore be integrated with any industry-standard gas monitoring control unit. Alternatively, the GD131 Refrigerant Gas Detector’s output can be used as a preset alarm relay to operate local warning or control devices.
The use of the GD131 Refrigerant Gas Detector in a refrigerant gas detection system will drastically reduce the amount of gas losses in refrigeration and air conditioning systems. This gas detector requires no further calibration after being factory-set, is self-checking and failsafe.
