0 - 25 bar (standard range), SS bourdon tube and wetted parts, dry, solid front blowout back with safety glass, 4-1/2" black fiberglass re-enforced plastic case, 1/2" NPT connection if you're in NA
Just a standard process gauge ±0.5% Accuracy
You may want a liquid fill if it's connected to any rotating machinery but for gas service it's normally dry.
