Double Scale for Air Compressor Pressure Gauge

The 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. Hongqi Instrument (Changxing) Co., Itd has put into operation. Thanks to efforts of 15 offices and more than 100 agents, our products are popular across the country, and are exported to over 10 Mid-East and Euro-American countries and regions. In 2000, we were recognized as enterprise name without administrative divisions by state administration for industry and commerce, and can do import and export business.
