Spectrex 20/20ML Mini UV/IR Flame Detector

The Spectrex 20/20ML UV/IR Flame Detector is low-cost, lightweight and compact. It comprises both UV and IR sensors, detecting hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires at distances up to 50 ft (15 m). The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.
