Dwyer 2004 – Magnehelic Differential Pressure Gauge, Range 0-4.0″ W.C., Minor Divisions 0.10

Select the Series 2000 Magnehelic ® Differential Pressure Gages for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s 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 weatherproof to IP67.

Select the –HA High Accuracy Magnehelic gage option for an accuracy within 1% of full-scale. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.
