Description

The Dwyer Differential Pressure Gauges boasts Magnehelic gauge movement that quickly indicates low air or non-corrosive gas pressures — either positive, negative (vacuum) or differential. The design of this Dwyer Differential Pressure Gauge resists shock, vibration, and overloads. The mechanism has no manometer fluid to evaporate, freeze or cause toxic or leveling problems. On top of all these benefits, the Dwyer Differential Pressure Gauges are very competitively priced.
