Micrometers (otherwise known as micrometer screw gauges) are essential measurement tools used extensively in the mechanical engineering sector along with other technical trades. As their name suggest these devices enable technicians to take very small and accurate measurements of components down as low as 0.001 inch on a standard 1-inch micrometer. Micrometers have a similar look and operation to a caliper in that it has opposing ends joined by frame. The object to be measured is then placed between spindle and anvil and a reading taken.
Modern digital micrometers feature electrical circuits, which allow for digital measurement and exceptionally accurate reading, although we still see many analogue devices pass through our lab on a regular basis. Like every other measuring instrument micrometers are exposed to changes in temperature, humidity, pressure and heavy use which can impact on their performance against specification.
To make sure a micrometer returns accurate measurements consistently it will need to be regularly calibrated. Most manufacturers recommend a 1 year micrometer calibration period, but it is important that the device is looked after with regular cleaning and verification by technicians between these annual calibration services.
Owing to the accuracy of these devices our micrometer calibration service benefits from highly accurate test standards and procedures performed both in our County Durham based laboratory and onsite at customer premises.
