Filter Monitoring
Air Velocity with Dwyer Pitot Tube
Fan Pressure Indication
Duct, Room or Building Pressures
Clean Room Positive Pressure Indication
Select the Magnehelic Gage for high accuracy--guaranteed within 2% of full scale--and for the wide choice of models available to suit your needs precisely. Using Dwyers simple, frictionless Magnehelic Gage movement, it quickly indicates low air or non-corrosive 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. Its 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.
