Calibration and validation

Calibration of measuring instruments is required wherever they are used in quality-related areas. Even the slightest of measurement errors can drastically affect the safety of production processes, or product quality.

Calibration of measuring instruments

Calibration – more accuracy and safety

Calibration involves the comparison of the reading by the instrument being calibrated with that of a reference instrument (also called reference standard) in specific conditions. Other important aspects of calibration include documenting the deviation recorded between the measuring instrument being investigated and the reference standard, calculating the resulting measurement uncertainty, and creating the calibration certificate recording this uncertainty.

Considerable contribution towards quality assurance

The calibration of measuring instruments therefore makes a considerable contribution towards quality assurance and the prevention of rejects, reworking, or claims for compensation.
