Dywer´s Magnehelic

Select the Dwyer® Magnehelic® gage for high accuracy — guaranteed within 2% of full scale — and for the wide scope of ranges, starting at 60 Pa. Using Dwyer's simple, frictionless Magnehelic® gage movement, it quickly indicates low air or noncorrosive gas pressures — either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too.

The Magnehelic® gage 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.
