Magnehelic Differential Pressure Gauge

Magnehelic Differential Pressure Gauge


We provide a comprehensive range of Magnehelic Differential Pressure Gauge which is diaphragm operated. The Magnehelic Differential Pressure Gauge is used in applications for measuring positive, negative, or differential pressure with an accuracy of 2%. Besides, Magnehelic Differential Pressure Gauge is also applied for monitoring filter status, duct static pressure, room pressure, fan or blower pressure, paint booths, dust collectors, cabinet purging and many others. The Magnehelic Differential Pressure Gauge runs on air and non-combustible compatible gases and comes with the option of natural gas. In addition to this, Magnehelic Differential Pressure Gauge is fabricated by using die cast aluminum case and bezel, with acrylic cover. Magnehelic Differential Pressure Gauge offered by us has exterior finish with grey color to withstand 168 hour salt spray corrosion test.
