Pressure gauges designed for low pressures measured in PSI, OSI (ounces per square inch) or inches of water column have very senstitive bourdon tubes and linkage. As with most of our gauges, low pressure gauges can be offered in a variety of materials, sizes and connection types. Low pressure gauge ranges include compound ranges with inches vacuum to positive pressure.
Some available features include an adjustable pointer, glow-in-the-dark dials, tempered glass lenses and solid front (blow-out back) cases.
