Description
The Dwyer Instruments 2020 Magnehelic Differential Pressure Gauge is a mechanical pressure meter measuring instrument that indicates the difference between two connected points. Its measurement range is 020″ WC allowing the gauge to display differential pressure within that specified range in HVAC systems. The instrument uses a diaphragm-based sensing mechanism that responds to the pressure variation between its inlet connections and translates that movement into a readable dial indication. It can be used to monitor pressure connections across air-handling components filters, ducts or other sections where differential pressure provides an operating measurement.
