Alloy Steel Magnehelic Differential Pressure Gauge, Certification : ISI Certified

Magnehelic Differential Pressure Gauge that we provide it quickly indicates low air or non-corrosive gas pressures, either positive, negative (vacuum) or differential. The design of our Magnehelic Differential Pressure Gauge resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. The Magnehelic Differential Pressure Gauge is used to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls & automatic valves, and monitors blood and respiratory pressures in medical care equipment. Magnehelic Differential Pressure Gauge should not be used with hydrogen gas as it can result in hazardous reactions.
