Dwyer Magnehelic Pressure gage/manometer

Dwyer\'s Magnehelic quickly indicates low air or non-corrosive gas pressures - either positive, negative (vacuum) or differential. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. Widely 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.
