Net Safety's hydrogen flame detector is specially tuned for non hydrocarbon flame applications that require precise and real-time detection of difficult to detect hydrogen and silane flames. Our advanced optical sensors ensure the highest match between the UV and IR spectral bandwidth and the radiation energy emitted by invisible hydrogen and silane flames - with the lowest match to non flame stimuli. This can provide ultra fast alarms, unparalleled false alarm immunity, and a full 120 ° horizontal field of view!

UVS-H2 and UV/IRS-H2 are packaged in sturdy explosion-proof enclosures, designed for extreme applications, and use the latest microprocessor sensor technology. They can operate independently or be connected to various control devices to build a reliable flame monitoring system. On site users can define sensitivity and time delay settings to further improve false alarm immunity, and the built-in testing routine ensures its continuous operation.

UVS-H2 and UV/IRS-H2 are highly suitable for professional applications where response time and wide field of view are crucial - industrial and commercial sites that use hydrogen fuel cells, hydrogen generators, hydrogen filling stations, and storage tanks, as well as semiconductor facilities that are often at risk of silane combustion.

The excellent UV/IR-H2 and UV-H2 flame detectors designed by Net Safety have been specially tuned to detect invisible H2 and silane flames. They are easy to operate and maintain, and can meet all safety and performance requirements for high-risk industrial installations! ​​

The field of view can reach 120 degrees, and the response time is less than 6 seconds!
