H2scan - Model HY-ALERTA 2620 -Explosion Proof Area Hydrogen Monitor
H2scan’s 2620 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 low flammability limit. The monitor is designed for either ceiling or wall mount. H2scan’s hydrogen-specific sensor technology has no cross sensitivity to other combustible gases, thus eliminating false positive alarms and ensuring safety system reliability.
