Dwyer Instruments 2030 Pressure Gage 319847-401 If primary voltage is presentThe Dwyer Instruments 2030 Pressure Gage is a field proven Magnehelic differential pressure gage engineered for high accuracy monitoring of air and non combustible gases. Designed for the rigors of HVACR environments, this 0 30. 0" w. c. pressure gauge utilizes a frictionless movement with a cobalt magnet and a silicone rubber diaphragm to provide a rapid response to low differential pressure changes. The 4" diameter dial face features a clear,
