How often should instruments be calibrated [update] - Beamex blog

How often should instruments be calibrated? That is a question we get asked often. It would be nice to give a simple answer to that question, but unfortunately, that is not possible. Instead, there are several considerations that affect the answer of a correct calibration period. In this post, I will discuss these considerations.
