WIKA 233.50 diaphragm seal pressure gauge, 0-1 bar range. Diaphragm-isolated pressure gauge for corrosive, viscous or particle-laden media where a direct-tube Bourdon gauge would foul. 316 SS wetted parts, dial size 100 mm, glycerin-filled for vibration damping. Applications: chemical process, oil-refinery, marine bilge and ballast systems. See our WIKA 232 / 233 pressure gauge selection guide for the full range of accuracy and connection variants.
