Description
The Dwyer 2304 Magnehelic Differential Pressure Gage is a trusted, precision instrument engineered for accurate measurement of differential pressure in HVAC, industrial, and mechanical systems. Featuring a zero-center range of 2-0-2″ w.c., this gage is ideal for applications requiring bidirectional pressure monitoring — such as filter status, fan performance, clean room environments, and airflow balancing.
Built around Dwyer’s renowned Magnehelic sensing technology, the 2304 delivers reliable, repeatable readings with a frictionless, helix-free movement that resists shock, vibration, and overrange conditions. The large 4″ diameter dial face ensures clear, at-a-glance readability from a distance, while the 1/8″ Female NPT process connections simplify installation into standard piping or tubing configurations.
