Select the Magnehelic gage for high accuracy--guaranteed within 2%
of full scale--and for the wide choice of 81 models available to
suit your needs precisely. Using Dwyer's 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. 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.
