Mechanical calibration

The physical and chemical laboratory is a professional laboratory subordinate to the metrological calibration division of Penney testing group. It has strong physical and chemical testing strength, and is equipped with a large number of primary and secondary reference materials and high-precision measurement standards. At present, the calibration standards of ion chromatograph, ICP emission spectrometer, pH (acidity) meter, atomic absorption spectrophotometer and atomic fluorescence photometer have been established. The laboratory has a professional technical team and engineers have rich practical operation experience and technical ability. As a member of the physical and Chemical Metrology Technical Committee, the physical and chemical laboratory has always been in the forefront of measurement technology, providing professional measurement and calibration services for customers.

At present, the main service areas cover food, medicine, metallurgy, petrochemical, construction, machinery manufacturing and other fields.
