All Stainless Steel Pressure Gauges
B131 series
Applications:
Used with all liquid and gas process media, provided that these do not corrode stainless steel, do not crystallize and are not highly viscous. The glycerin/silicon oil filled type is especially used for measuring points subject to vibration and highly dynamic pressure load. Particularly used in chemical, petrochemical, food industry, biochemistry and any rush industries.
