Pressure Gauges

Movable dial with blue pressure markings and red temperature markings make the instrument easy to read. Pressure is indicated in both psi and kPa, while temperature is measured in both Fahrenheit and Celsius. Series TRI comes in three different connection options including lower mount, center back mount, and center back mount with extension shank.

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.
