Laser Based – Fixed Point Gas Detection is an Enhanced Sensing Element that thrives where Traditional Gas Detection technologies do not survive.

The Remote Point (RPX) Probe used with Boreal Laser’s line of GasFinder3 Based Instruments is primarily used in process monitoring & control applications for its quantitative performance in difficult applications, fail-safe design for safety critical applications, and its maintenance friendly operation.
