The Spectrex 20/20L (and LB) combined UV/IR Flame Detector employs a solar blind UV sensor coupled with a narrow band IR sensor to provide excellent sensitivity combined with enhanced immunity to false alarms (solar blind).
This Spectrex Flame Detector has a 20msec response to a saturated signal. Detects hydrocarbon based fuel and gas fires, hydrogen, hydroxyl fuels, metal and inorganic fires.
