    HYDROGEN AS TRACER GAS FOR LEAK DETECTION M. Block1 1 Sensistor Technologies GmbH; Muehlheim am Main, Germany Abstract: Helium is the most commonly used tracer gas for leak detection. However, it has a number of limitations in many industrial applications. The molecular weight of hydrogen is only half that of helium, and hydrogen has a. Avoid an outage with new hydrogen leak detection technology Maintenance of hydrogen-cooled generators is critical for the safe and efficient operation of a power plant. Finding and repairing hydrogen leaks from the cooling system is one aspect that can require exhaustive searches on components, valves, fittings, or other locations.

    HY-ALERTA™ H2scan's Explosion Proof Area Hydrogen Monitor provides hydrogen-specific leak detection and measurement for hydrogen concentrations as low as ppm and can be scaled to any concentration up to 5% hydrogen by volume, a range representing 10% to % of hydrogen's low flammability limit. Experts in Hydrogen (H2) Gas Detection Battery Room Hydrogen Detection. Battery room safeguards are not generally well understood and yet as UPS systems see much more common use in data centers and Telcom, proper design, ventilation and other safeguards must be incorporated for safety, reliability and loss prevention.
