FlameGard® 5 UV/IR-H2 Flame Detector

The precision-crafted MSA FlameGard® 5 UV/IR-H2 Flame Detector monitors the ultraviolet and infrared spectral ranges to detect unwanted hydrogen fires. Its meticulous engineering and usage of UV and IR make it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation. The unit’s continuous Optical Path Monitoring (COPM) checks both the optical path integrity and the detector’s electronic circuitry once a minute, while the wide field of view enables greater fire detection coverage.
