Calibration Service

Precise work with measurement technology requires technically flawless equipment. However, changing ambient conditions and thermal, mechanical or chemical stresses can lead to inaccurate measurements as the devices are used over a longer period of time.

In order to ensure the reliability of the measurement results and to ensure the longevity of the measuring devices, we recommend regular calibration. For this we offer you our calibration service with test certificate. The acceptance test certificate according to DIN EN 10204:2004/3.1 shows the data of the reference measurement, the calibration values and the measurement uncertainty, confirms the connection to national measurement variables and thus certifies the quality of your measuring equipment.

Calibration means checking the correctness of the measured variables of a measuring device or determining measurement deviations. The calibration takes place without any technical intervention in the measuring system.

Advantages

Reproducibility of measurements
Increasing the acceptance of measurement results
Traceability to national standards
Increase in quality level
