In recent years, with the widespread application of computer technology, optoelectronic technology, digital technology, microprocessing technology, image display technology, automation technology, intelligent technology, etc., mechanical metrology has made a new leap. A large number of measurement standard devices with wide range and high accuracy have been established both domestically and internationally, involving mechanical quantities such as quality, vibration, pressure, force value, flow rate, etc., and are widely used in industrial and agricultural production, national defense construction Scientific research, domestic and international trade, healthcare, and various fields of people's lives. We are equipped with precision instruments and standard components such as first-class piston pressure gauge, E1 grade weight, mass comparator, 0.1 grade standard force measuring instrument, energy generator, spring impact hammer energy generator, torque tester, material testing machine, standard speed device, pressure calibration device, millionth precision level, micro differential pressure verification device, vibration impact analysis system, etc.
