Select the Dwyer® 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.

A single case size is used for most models of Magnehelic® gages. They can be flush or surface mounted with standard hardware supplied. Although calibrated for vertical position, many ranges above 1" may be used at any angle by simply re-zeroing. However, for maximum accuracy, they must be calibrated in the same position in which they are used. These characteristics make Magnehelic® gages ideal for both stationary and portable applications. A 4-9/16" hole is required for flush panel mounting. Complete mounting and connection fittings, plus instructions, are furnished with each instrument.
