Testo Calibration Services

Calibration and validation

Calibration of measuring instruments is required anywhere 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: increased precision and reliability

Calibration involves comparing the reading of an instrument being calibrated with that of a reference instrument, under specific conditions. Other important aspects of calibration include documenting the deviation recorded, calculating the resulting measurement uncertainty and creating the calibration certificate recording this uncertainty. The calibration of measuring instruments is therefore an essential part of quality assurance, contributing to the prevention of rejects, reworking, or claims for compensation. Your local authorized Testo partner will be happy to advise you on the various calibration services available for Testo measuring instruments. Calibration of other manufacturers measuring instruments is also possible.
