Dwyer Instruments 2304 Magnehelic Differential Pressure Gauge 2" To 0-2" WC

The Dwyer Instruments 2304 Magnehelic Differential Pressure Gauge is a high-accuracy part is used in HVAC systems to measure low-differential pressure that is within the range of 2”w.c–0– 2”w.c. This gauge uses a distinct diaphragm action and translates pressure variations into linear motion, which can be read from the face of the gauge. It is widely used in HVAC systems to measure the airflow rate and filter differential pressure, for control and energy conservation. The gauge construction is shock and vibration-proof and is suitable for use in clean rooms and laboratories. Advantages of the Magnehelic gauge include it is highly sensitive pressure to small pressure changes, no need to use manometer fluids that may evaporate or freeze.
