Magnehelic Gauge



Magnehelic gauges are used for high accuracy readings. They quickly indicate low air or non-corrosive gas pressures, either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. 




The Magnehelic gauge is the industry standard 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 and automatic valves, and monitors blood and respiratory pressures in medical care equipment.
