High Performance Hydrogen Flame Detection
Designed for hazardous industries where fast hydrogen flame detection is critical and nuisance alarms are not an option. This detector comes with a huge detection range without sacrificing an inch of accuracy.
Excels in Harsh Conditions
Never worry about putting your system to the test. Engineered to endure extreme weather conditions, the FDS303H remains reliable through snow, ice, and condensation.
Long Distance Detection
Cover every inch of your operation, with fewer units needed than ever before. This detectors cutting edge IR-sensor has been independently tested to demonstrate it can detect a hydrogen plume fire at a record high 40m (131 ft) in 5 seconds.
Self-Monitoring Technology
Maintenance prediction and early warnings take the guesswork out of the equation. The sensor accomplishes this by automatically measuring dirt on the lens with IR technology, which is immune to sensor poisoning. This preventive technique also eliminates the risk of measuring drift.

The MICROPACK FDS303 is an explosion proof
multi spectrum IR flame detector. The device
delivers superior performance, responding to
hydrocarbon liquid fuel and gas fires at long
distances.
The FDS303 complements the CD-F-301 and
CD-F-300 Visual Flame Detectors by delivering
superior performance in the detection of
hydrocarbon fires which are not detectable in the
visible spectrum. The FDS303 utilizes the latest IR
flame detection algorithms to ensure maximum
false alarm immunity.
