GD10L Open Path Infrared Hydrocarbon Gas Detector

Yleiset

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 (6.5 feet) to 30m (100 feet).
The IR sources are more resistant to vibration/shock than competing technologies, hence replacement of the IR sources is not necessary during it’s long service life.
The unit combines a transmitter / receiver into a single housing and utilises a novel retro-reflector. The whole system can be commissionable by a single person. 
The retro-reflector is heated to minimise condensation and icing.
5 years warranty, 15 years on IR sources
