Dwyer Magnehelic® 2000 Series Low Differential Pressure Gauge

Dwyer Magnehelic gauges are ideal for both portable and stationary applications, measuring fan, blower, and fluid system pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, and liquid levels with bubblers.

Using simple, frictionless Magnehelic movement, the gauge quickly indicates low air or non-corrosive gas pressures: positive, negative, or differential. The design resists shock, vibration, and overpressure, and has no manometer fluid to evaporate, freeze, or cause toxic or leveling problems.

Key Specifications
