How frequently need the devices be calibrated?

The calibrating periods from the point of view of general metrology determins the user of the meter, or the metrologist from the company, who decides about the period during which the calibration is valid, based on frequency of usage of the device and monitoring of the data from previous calibratoins. It is also necessary take into account relevant standards for NDT, where can be found independent recommendations for calibration frequency for your devices. Generally speaking, most of our customers calibrate their devices once a year. In aerospace industry is the calibration interval ordinarily shortened for 1/2 year.
