Shanghai Precision & Scientific Instrument Co., LTD is a professional analytical instruments manufacturer, located in China. We are involved in the R&D, manufacture and supply of a vast array of high precision analytical instruments, physico-optical instruments and electrochemical instruments, including spectrophotometer, fluorescence spectrophotometer, atomic absorption spectrophotometer, chromatograph, flame photometer, refractometer, polarimeter, melting point apparatus, light chromaticity instrument, pH meter, conductivity meter, dissolved oxygen meter, ion meter, multi-parameter meter, automatic potential titrator, environmental analyzer, sensor, and more. We produced the first spectrophotometer, pH meter and polarimeter in China. Due to our product manufacturing and management practices in rigid compliance with international standards, we are ISO9001:2000 and ISO14001:1996 approved.








Our analytical instruments, physico-optical instruments and electrochemical instruments have found countless applications in the fields of petrochemical, metallurgy, mining, power plants, environmental protection, medical and health, to name a few. For example, by means of analyzing absorbance, our spectrophotometer can be used for quantitative analysis and qualitative analysis of substances. In addition to conducting quantitative analysis and qualitative analysis, our gas chromatograph is suitable for measuring physical and chemical constants like partition coefficient, activity coefficient, molecular weight, specific surface area, and others, of gas components in the stationary phase. Our flame photometer is a ideal choice for you to check the calcium content in beer, milk, juice, and biscuit, etc., or the potassium content in fertilizer or soil, or sodium content in fuels like crude oil, gasoline, and diesel, etc.
As to our polarimeter, it is utilized to measure the optical rotation and analyze concentration, content and degree of purity of substances and widely applied to chemical examination or quality control in pharmaceutical, drug test, sugar production, food, spice, chemical, petroleum, scientific research, teaching, and other fields. Used for precision measurement of pH values of liquid media, the pH meter is indispensable inspection equipment for food factories and waterworks to be QS and HACCP approved.
While continually improving products and technologies, we offer indoor environment examination, food hygiene test, soil testing and fertilizer recommendation system, air and water quality real-time monitoring system, and other solutions, so we can accommodate increasing customer needs in the market.
