H2scan’s HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor provides 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 lower flammability limit. The monitor is designed for either ceiling or wall mount and has an RS422 capability that extends the
interface from the Sensor Module to the Control Module to several hundred feet. H2scan's hydrogen-specific sensor technology has no cross sensitivity to other combustible gases, thus eliminating false positive alarms and ensuring safety system reliability.
