Companies that require calibration services on their tools and equipment must choose in house calibration could be a mistakefrom two main delivery methods. These are “in-house calibration,” where the company itself provides the calibration, and “external calibration,” where the company outsources the work to a calibration lab; preferably one that is reputable and accredited.
Although some companies prefer to take a burden of responsibility by internally calibrating their own instruments, it’s not recommended. Establishing an in-house calibration service adds up to a significant investment, having to purchase facilities, equipment and trained personnel. Many calibration environments require temperature controlled rooms, strict organization, and other particular conditions. Additionally, the instruments required to do internal calibration must be certified themselves and meet NIST standards.
Why would you go through the hassle of in-house calibration? Why suffer through getting the instruments needed for calibration certified, in addition to purchasing these instruments and training personnel to use them, when you could just outsource the original instruments that need calibration and avoid the extra legwork, cost and wait.
The bottom line is that internal calibration adds up to a considerable use of time, money and resources. To ensure the accuracy and dependability of your instruments, it is often best to leave your calibration to experts at a certified calibration lab.
