FL500-H2 UV/IR Flame Detector (Hydrogen Applications)

FL500-H2 UV/IR Flame Detector (Hydrogen Applications)

This ultraviolet/infrared flame detector is designed to detect hydrogen fires. The optical flame detector monitors for radiation emitted by a hydrogen flame in both the ultraviolet (UV) and infrared (IR) spectral ranges. It helps you get fast response time and increased false alarm immunity against sources of radiation.
