Calibrating Micrometers: Your Questions Answered

Micrometer Calibration

Micrometers can be found in many different quality departments. Micrometers are used to measure thickness, diameters, and depth of slots with small distances. Reoccurring calibration of your micrometer using a certified micrometer calibration service guarantees the precise readings you need to meet safety and compliance standards, while on the jobsite. Errors that arise from using uncalibrated or damaged equipment may result in costly consequences that can affect you or your employees.

Micrometer Calibration

Why do micrometers need calibration?

Calibration of your micrometer verifies and/or restores the accuracy of your equipment back to proper working conditions. Periodic calibration of your micrometer retains the integrity of the instrument’s readings and guarantees consistent measurements. It is important to get your micrometer calibrated in a timely manner according to manufacturer’s standards, however this calibration is only beneficial when it is done accurately. JM Test Systems offers quick and affordable micrometer calibration solutions to meet most any requirements.

Whether you need your equipment to meet certain compliance standards or you are trying to determine the measurement of a miniscule part, you need to be confident in your micrometer’s calibration and ability to perform. To ensure that your micrometer is calibrated accurately, you should have your calibration done by an accredited lab like JM Test Systems. All of our calibrations are performed to elite levels of accuracy and follow strict laboratory standards that coincide with our accreditation, as well as our commitment to excellent customer service.

How often should micrometers be calibrated?

In order to maintain the integrity of your micrometer, it must be monitored and calibrated on a regular basis. The corresponding time period is known as the calibration interval. The calibration interval of a micrometer is dependent on many factors including the measured quantity and allowable tolerance range, the level of stress to which the micrometer has been subjected, the required measuring accuracy, the stability of past calibrations and the quality assurance requirements. Speedy calibration checks can be with a set of gage blocks before each use.

How to calibrate micrometers?

When calibrating a micrometer, the standard accuracy must be greater than a 4:1 ratio over the accuracy of the gage being calibrated. The gage block must have a certificate of NIST traceability to have an accurate standard. Gage blocks are calibrated to a specific tolerance which has an accuracy greater than the accuracy of the micrometer. Each calibration comes with a data sheet of the recorded measurements taken during the calibration of the instrument. By looking at this data, one can calculate the deviation of error, if any, of the micrometer and add or subtract this while making measurements.

Where to get micrometers calibrated?

JM Test Systems calibrates, repairs and even sells micrometers. We are a leader in a wide range of dimensional calibrations. JM Test provides different services for precision length-measuring devices through our multiple ISO-17025 laboratories located across the United States. We provide certifications that are traceable to the SI unit through NIST for digital, standard and specialty micrometers. All calibration services are performed to JM Test System’s highest level of accuracy and laboratory standards. JM Test offers a full array of trusted solutions with the convenience of selecting from our in-lab or onsite dimensional services. Our in-lab technicians can calibrate your micrometer and a wide range of other equipment at one of our multiple labs located in Louisiana, Texas, and Illinois, or, depending on where you are located, our on-site calibration team can come to you.
