FDS303H Multi-Spectrum IR H2 Flame Detector

Designed for hazardous industries where fast H2 flame detection is critical and nuisance alarms are not an option.

The MICROPACK FDS303H is an explosion proof multi spectrum IR hydrogen (H2) flame detector. The device delivers superior performance, responding to hydrogen fires at long distances.

The FDS303H has been independently tested to demonstrate it can detect a hydrogen plume fire at 40m (131 ft) in 5 seconds.

About the product

The FDS303H compliments the FDS series of Visual and IR3 Flame Detectors by delivering superior detection performance of hydrogen (H2) fires. The FDS303H utilizes the latest IR flame detection algorithms to ensure maximum false alarm immunity.
