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
product highlights
bezel provides flange for flush mounting in panel.
clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.
precision litho-printed scale is accurate and easy to read.
red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft.
pointer stops of molded rubber prevent pointer over-travel without damage.
"wishbone" assembly provides mounting for helix, helix bearings and pointer shaft.
jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion damped with high viscosity silicone fluid.
zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness.
helix is precision made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale.
