Differential Pressure Gauges
Measure the difference in pressure between two pressure points.
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 levelling problems. May be used with Hydrogen; order a Buna-N diaphragm, pressures must be less than 35 psi.
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.
Designed to give fast, accurate indication of differential pressures. The gauge may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure.
The 4-digit LCD can display readings in common English and metric units so conversions are not necessary. The simplified four button operation reduces set up time and simplifies calibration with its digital push button zero and span. All models are factory calibrated to specific ranges.
