Solid front, blow-out back case design meets safety requirements of ASME B40.100.
Iis an industrial type gauge suitable for corrosive environments where the fluid medium does not clog connection or corrode wetted part material. Solid front, blow-out back case design meets safety requirements of ASME B40.100.
The gauge is well suited for use in maintenance departments and test stands, as well as recertifying gauges and maintaining the accuracy of existing gauges in refineries and chemical plants.
