Plaque A-464

Series 2000

The Series 2000 Magnehelic® Gage is 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 noncorrosive gas pressures–either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67.
