Dwyer Instruments 2000-0 Pressure Gage 323613-751 Wide Flow Range: Operates efficientlyThe Dwyer 2000 0 Magnehelic Gage is the industry standard for monitoring differential pressure in commercial HVAC systems, offering a precise range of 0 0. 5" w. c. with an accuracy of 2% of full scale. Engineered for longevity in demanding environments, this analog pressure gauge utilizes a frictionless Magnehelic movement that eliminates wear and hysteresis common in mechanical linkages. The diaphragm actuated design is compatible with air and non
