• Indicate positive, negative or differential, accurate within 1% Exterior finish is coated gray to withstand 168 hr salt spray corrosion test Easy to read gage through undistorted plastic face permits viewing from far away Patented design provides quick response to pressure changes means no delay in assessing critical situations Durable and rugged housing and high-quality components combine to provide long service life and minimized down time High-accuracy option is twice as accurate as the standard magnehelic gage 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 Jewelled 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 Calibrated range spring is flat spring steel, small amplitude of motion assures consistency and long life, it reacts to pressure on diaphragm, live length adjustable for calibration Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates, it is locked and sealed in position with a sealing plate and retaining ring, diaphragm motion is restricted to prevent damage due to overpressures Die-cast aluminum case is precision made and iridite-dipped to withstand 168 hr salt spray corrosion test, exterior finished in baked dark gray hammerloid, 1-case size is used for all standard pressure options and for both surface and flush-mounting Over pressure protection O-ring seal for cover assures pressure integrity of case

Select the Series 2000 magnehelic gage for a versatile low differential pressure gage with a wide choice of 81 model and 27 options to choose from. Using Dwyer® simple, frictionless magnehelic gage movement, it quickly indicates air or non-corrosive gas pressures either positive, negative (vacuum) or differential. The design resists shock, vibration, over pressures and is weather-proof to IP67. Select the HA high-accuracy magnehelic gage option for an accuracy within 1% of full scale, located below in the product configurator. Also included with the HA option at no extra cost are a mirrored scale overlay and a six point calibration certificate.
