Differential Pressure Gauges

These gauges measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drops and pressure in fluidic systems. Find a wide selection of meters and gauges to fit your specific application.


Dwyer 2000 Series Magnehelic Differential Pressure Gauges-

Dwyer 2000 Series Magnehelic Differential Pressure Gauges

Quickly indicates low air or non-corrosive gas pressures either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. May be used with Hydrogen; order a Buna-N diaphragm, pressures must be less than 35 psi.


Dwyer 2-5000 Series Minihelic II Differential Pressure Gauges-

Dwyer 2-5000 Series Minihelic II Differential Pressure Gauges

This compact gauge is easy to read and can safely operate at total pressures up to 30 psig. Standard pressure connections are barbed fittings for 3/16" ID tubing; optional 1/8" male NPT connections are also available. Over-pressure protection is built in by means of a blow-out membrane molded in conjunction with the diaphragm.
