Double Scale Gas Pressure Gauges
Copper tube ordinary pressure gauge, suitable for measuring liquid, gas, steam, etc.
Y series 2.5 accuracy class pressure gauge can be applied for those gaseous, liquid or vaporous media which don' t explode, crystallize and freeze, and corrode stainless copper or copper alloy. It adopts helical case, standardized copper connector, broadened bourdon tube, stainless steel movement and strengthened link.In order to ensure accuracy class, advanced equipment and technique are used in the process of calibration and testing.
It is characterized by good appearance, high precision, small distance after tapping, good repetition and long service life.
