The Fike FIK-IR3-H2-HD-AS11 is a triple IR (IR3) hydrogen flame detector with high-definition video output, for fast, reliable detection of hydrogen fires in all weather and light conditions.
The integral HD camera gives clear images of the protected area, so responders can see the situation before entering. This version has M25 conduit openings.
