20/20 L (&LB) UV/IR Flame DetectorThe Model 20/20L (& 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). The detector has a 20msec response to a saturated signal.

Detects hydrocarbon based fuel and gas fires, hydrogen, hydroxyl fuels, metal and inorganic fires.
