Hydrogen Detector – Catalytic Combustion Type
FH2-HY04、FH2-HY05、FH2-HY06、FH2-HY11、FH2-HY11-HC
Fast start‑up, high durability hydrogen detector proven in mass‑produced FCVs
This hydrogen detector is designed for hydrogen‑powered systems such as fuel cell vehicles (FCVs) and stationary energy equipment. It features an original catalytic combustion sensor that enables start‑up within one second and response within three seconds, meeting strict automotive safety requirements. With excellent hydrogen selectivity, it minimizes false detection caused by interference gases such as ethanol or methane. The detector also offers high durability and long‑term stability, compliant with global automotive standards. It is the first hydrogen detector adopted in mass‑produced FCVs, supporting safe and reliable hydrogen utilization.
