H2-BF Hydrogen Sensor

H2 Gas Sensor, Electrochemical, B-Series, 0–5,000 ppm filtered
Extended-range hydrogen sensor for fixed leak detection and process monitoring

The H2-BF is a 0–5,000 ppm hydrogen sensor in the B-Series format, suited to fixed leak detection, fuel-cell systems, battery storage and process gas monitoring. It offers 10–25 nA / ppm sensitivity at 400 ppm H2, T90 < 55 s and a large filter capacity (> 250,000 ppm·h H2S), enabling robust operation in demanding mixed-gas environments. Operating life exceeds 24 months (24-month warranted), providing dependable, long-term hydrogen monitoring.
