There are two main delivery methods when it comes to calibration of instruments, no matter what industry it relates to. “In-house” calibration refers to the process of a company choosing to perform calibration on their own. They may have engineers who are trained in calibration who can properly adjust the necessary instruments. “Outsourced” calibration refers to a third-party laboratory that specializes in calibrating instruments. Ideally, the labs are certified and accredited, a company can send their instruments for calibration. There are pros- and cons- to each method, especially depending on the specific needs of a company.
Choosing which method to use relies on how much money you are willing to invest in the instrument, what your use of the instrument will be, how often the manufacturer recommends calibrating the instrument, whether you need the instrument calibrated to a standard and whether you have employees trained in calibrating instruments.
