Boreal Laser Based Open Path Detection
Laser Based – Open Path Gas Detection is an Enhanced Sensing Element that thrives where Traditional Gas Detection technologies do not survive.

The Open Path (OPX) Head used with Boreal Laser’s line of GasFinder3 Based Instruments is primarily used in leak detection, industrial health & hygiene, leak detection & repair (LDAR), and ambient monitoring applications for its quantitative performance in difficult applications, fail-safe design for safety critical applications, and its maintenance friendly operation.
