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.

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.

Offers 0.5% FS accuracy in a rugged, easy-to-use unit, and feature user-selectable units of measurement, allowing one gauge to be used for a variety of pressure scales. The DPGWB gauges stainless steel wetted material makes it suitable for a wide variety of liquids or gases. It comes equipped with a protective rubber boot.

The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background.
