The Dwyer 2000-500PA-BA differential pressure gauge is part of the 2000 series.
It is well-designed to resist shock, vibration, and overpressure, and is waterproof with an IP67 rating. Featuring a frictionless Magnehelic® measuring mechanism, it can quickly and accurately indicate positive, negative (vacuum), and differential pressures of air or non-corrosive gases.
Typical applications include filter monitoring, air velocity measurement with a Pitot tube, blower vacuum monitoring, fan pressure indication, duct or room pressure, and clean room positive pressure indication, playing a vital role in various industrial and commercial scenarios.
