Spectrex 20-20U UV Flame Detector

The Spectrex 20-20U (ad UB) UV Flame Detector responds to high energy UV radiation emitted by fires and by explosions at the point of ignition. Detects hydrocarbon-based fuel and gas fires, invisible hydrogen flames, hydride, ammonia, silane and other inorganic fuel fires. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.
