Differential pressure gauges

It quickly indicates low air or non-corrosive gas pressures. The Low Pressure Differential gauge or also know as Magnehelic gauge is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates.

Differential gauge is used to measure the pressure difference under the same conditions. It is mainly used in petrochemical, pipelines and other areas.
