H2Scan HY-ALERTA 600B Fixed Area Hydrogen Monitor

H2Scan HY-ALERTA 600B Fixed Area Hydrogen Monitor will provide hydrogen-specific leak detection and measurement for hydrogen concentrations as low as 4000 ppm and can be scaled to any concentration up to 5% hydrogen by volume, a range representing 10% to 125% of hydrogen’s low flammability limit.

They are designed for either ceiling or wall mount and have RS422 capability that extends the interface from the sensor to the controller to several hundred feet. H2scan’s hydrogen-specific sensor technology has no cross-sensitivity to any other combustible gases, thus eliminating false positive alarms and increasing system reliability.
