TDL – HF Gas Detection

home-slide-1

The GasFinder technology is ideally suited for numerous safety, environmental and process applications. The GasFinder systems is robust, reliable and require little maintenance; feature internal calibration & are ideal for critical applications.

The GasFinder can be configured as a multi-channel or single channel / portable system with a range of field mounted transmitters for either “Open area” monitoring or “stack / duct” emissions monitoring.

Fiberoptic cable carries the laser light to transmitter heads, which direct the beam along a path to a reflector. The return light is collected on a non-biased photodetector. The photo current is returned to the Central Control Unit using coaxial cable. The transmitter heads are therefore intrinsically safe. There are four available transmitter heads that can interface with the GasFinderMC CCU depending on the end user’s applications.
