- Gauge provides excellent readability in a compact size
Combining clean design, small size, and low cost with enough accuracy for all but the most demanding applications, the Minihelic® II gauge offers the latest in design features for a dial type differential pressure gauge . It is a very compact gauge but is easy to read and can safely operate at total pressures up to 30 psig. The gauge is designed for panel mounting in a single 2-5/8' diameter hole. Standard pressure connections are barbed fittings for 3/16' I.D. tubing. Over-pressure protection is built into the gauge by means of a blow-out membrane molded in conjunction with the diaphragm. Accidental over-ranging up to the rated total pressure will not damage the gauge . With removable lens and rear housing, the gauge may be easily serviced at minimum cost. With the housing
