Established in 2003 in Ningbo China, Rising Instrument Co Ltd is a professional manufacturer of industrial pressure and temperature measuring instrumentation according to standards including China GB/T, Europe EN 837, EN 13190 and US ANSI. With ISO9001 certified. It is 30 kilometers away from Ningbo Seaport and 260 kilometers away from Shanghai Pudong International Airport.The raw material is chosen according to relative international standard including ROHS. Spare parts are strictly made according to drawing and artwork.

Each gauge is tested by 130% pressure for leak and over pressure testing. Precision gauge is recalibrated every time before using. Each gauge is calibrated carefully and accurately and rechecked before final assembling and passes static pressure testing before packing. Each liquid filled gauge is packed in sealed plastic bag to ensure no leaking during shipment. Production serial number is marked on the gauge to keep chasing record. To keep better performance, some bourdon tubes and movements are imported from Germany. The raw material of bimetal sheet is made in Japan and US.
