Calwest Services offer repairs and servicing of micrometers to ensure reliable operation. We will clean, lubricate, and replace batteries as part of our calibration service.

If your micrometer is worn or damaged beyond repair, Calwest Services can supply a new micrometer with a traceable calibration report in accordance with Australian Standards.

To ensure accuracy and instrument reliability, Calwest Services recommends the following preventive maintenance and usage guide:

Usage Guide
  • Before using, wipe the measuring faces with a lint-free cloth, and ensure the object being measured is clean. Micrometers are a precision instrument, so measuring rusted or rough objects should be avoided.
  • When using micrometers, do not overtighten. Rotate the thimble to bring the measuring faces close, then carefully rotate the ratchet until you hear a click. It is best practice to measure several times to ensure an accurate measurement.
  • Due to thermal expansion and its negative effect on measurements, it is important to monitor temperature variations. Ideally, all measurements should be at around 20 degrees Celsius. However, for practical reasons, the vernier and the object being measured should be at the same temperature.
Preventive Maintenance
  • Wipe clean the measuring faces before use.
  • Using a lint-free cloth, occasionally apply a good quality 3-in-1 oil to prevent rust.
  • Do not force the spindle. A resisting spindle may indicate internal contamination, and forcing it could result in permanent damage. Your micrometer will need to be professionally inspected and cleaned.
  • Be mindful of your work environment. Keep the micrometer safe and away from ledges and other potential hazards, such as heavy tooling.
  • When not in use, leave a gap between the measuring faces.
  • Store the micrometer in a dry and humid-free place, preferably in its original protective case.
