Dwyer Instruments 2004 Pressure Gage 320819-301 reducing amp draw and mechanicalThe Dwyer Instruments 2004 Magnehelic Differential Pressure Gage is the industry standard for monitoring filter resistance, fan pressures, and duct velocity in commercial HVACR systems. Built with a rugged die cast aluminum housing and a 4 inch diameter dial face, this mechanical gauge provides a clear 0 4. 0" w. c. range with 2% accuracy throughout the scale. The frictionless Magnehelic movement utilizes a high precision cobalt magnet and a silicone
