The Spectrex 40/40I Triple IR (IR3) Flame Detector can detect fuel and gas fires from a long distance, and with the highest immunity to false alarms. The 40/40I IR3 can detect a small (0,1m2) gasoline or heptane pan fire at 65m in less than 5 seconds. The Spectrex 40/40I is one of the most durable and weather resistant Flame Detector on the market.
