Testing Center

The main work is as follows:

一,At present, 14 items of the highest measuring standards have been established for metrological verification, which have passed the examination of Dalian Municipal Bureau of quality and technical supervision. It can carry out measurement verification and maintenance of length, heat, mechanics and electricity, as well as geometric dimension measurement, tolerance and roughness measurement, coating measurement, etc.

1.Length measurement:

  • Gauge block calibration
  • Thread gauge calibration
  • Smooth mechanical gauge calibration
  • Calibration of frame level and bar level
  • Calibration of vernier measuring tools
  • Verification of micrometer measuring tools
  • Verification of meter measuring tools
  • Verification of angle ruler
  • Verification of square
