Information of Traceability

Takikawa Engineering Co.,Ltd.



  • Our Laser Micrometers(LDM series) and Surface Variation Detectors(TM series) are supplied after the calibration provided by the traceable pin gauge assured its accuracy by National Standard.
  • A calibration gauge pin and a gauge holder are available to supply as an option.
  • As our Laser Micrometers are adjusted and calibrated by combining Scanning Units and Display Units as a set, you are required to use those units with the same serial number.
