Description
The PRI is a general-purpose Bourdon tube pressure gauge designed for industrial pressure, vacuum and compound measurements. Its black zinc-plated steel case is available in 1.5″, 2″ and 2.5″ dial sizes, with bottom or center-back mounting configurations. Copper-alloy wetted parts and movement suit non-corrosive media, while acrylic, polycarbonate or glass windows are available. Measuring ranges extend from 0 … 1 bar to 0 … 400 bar and -1 … 30 bar. Optional oxygen-service cleaning, damped movement, high-temperature silver brazing and diaphragm-seal mounting support varied applications.
