GD10L Open Path Infrared Hydrocarbon Gas Detector

Brand: Detcon Inc

The GD10L provides an effective response to the detection of gas hazards in a wide range of industrial environments from boiler plant rooms to offshore petrochemical installations. 

The GD10L safeguards life, environment and property through reliable gas detection over path lengths from 2 meters (6.5 feet) to 30 meters (100 feet). 

The IR sources are more resistant to vibration/shock than competing technologies, hence replacement of the IR sources is not necessary during its long service life. 

The unit combines a transmitter/ receiver into a single housing and utilizes a novel retro-reflector. 

The whole system can be commissionable by a single person. 

The retro-reflector is heated to minimize condensation and icing.
