Magnehelic Differential Pressure Gauges
The iconic Dwyer Magnehelic gauge provides accurate, dial-type indication of positive, negative or differential air and gas pressures without the use of liquid.

The Magnehelic series is Dwyer's flagship differential pressure gauge, valued for its simple, rugged diaphragm-actuated movement and clear analog dial. It measures low ranges of air and non-combustible, compatible gas pressures and is a standard for monitoring filter loading, fan and blower performance and room pressurization.
Available in a wide selection of ranges and scales, the gauge offers an easy-to-read display, optional set-point pointers and switch versions for alarm and control functions.
