Dwyer Series SGZ 2.5″ Industrial Pressure Gage

The Series SGZ Industrial Pressure Gages have dual psi and bar (x100 kPa) scales with ±1.5% full-scale accuracy. The Series SGZ gages are designed with 304 SS housings and 316 SS wetted parts for excellent chemical compatibility. These gages cover a wide variety of ranges in either bottom or back connection configurations. Series SGZ gages employ an easy-open breather plug on top, which allows liquid filled units to breathe, relieving any built up internal pressures. Plug easily pops open and does not need to be entirely removed or cut like a typical gages’ rubber plug grommet.
