OMICRON Calibrations

first-class calibration service
for your testing equipment

Precise measurement results are only possible with testing instruments that have been calibrated correctly. However, the accuracy of each individual instrument changes over its product life. Therefore, it is essential to calibrate and if necessary, adjust testing equipment regularly depending on the area of application.


The need for ISO 17025-compliant calibrations has continued to grow over the years. In the meantime, calibrations according to ISO 17025 are standard requirements in some countries. On the other hand, the conventional ISO 9000 manufacturer calibrations are steadily losing acceptance. We can now cover this growing demand professionally.


With OMICRON Calibrations service, we have established a globally recognized, state-accredited ISO/IEC 17025 calibration laboratory that meets the highest international standards. Our goal is to provide our customers with the most accurate and complete calibrations possible.

Calibration, verification and adjustment - what's the difference?




Calibration only involves measuring physical quantities and comparing the measurement results from the test object with a suitable and traceable reference measuring instrument under defined, reproducible conditions.


Verification is a comparison of a device’s measurement results with limit values, e.g. the published tolerances and the interpretation of these results. This means that a statement is made as to whether the device is still within the tolerance range.


During adjustment, the deviation between the test instrument’s measured values and a reference instrument is reduced to a minimum or brought back within a defined tolerance range. This requires an intervention in the test instrument.

How often to calibrate?


Basically, there is no general rule as to when and how often a test instrument should be calibrated. Therefore, the user must decide for themselves whether their test equipment is still suitable for the application, whereby the manufacturer's recommendations are a good aid in determining the calibration intervals. An important factor is the test device’s field of application: for example, when it comes to meter tests different requirements apply to the test device than those that are used in the field of protection technology.


Calibrating testing equipment annually is quite common and useful, even if neither ISO 9001 nor ISO 17025 make it mandatory. On the other hand, the standards clearly require testing equipment to function with sufficient accuracy for an intended purpose.

What OMICRON Calibrations can do for you


In addition to the conventional performance of a factory calibration, OMICRON Calibrations cover calibrations according to ISO 17025. The results of the factory calibration are checked again by OMICRON Calibrations as a legally independent body. OMICRON Calibrations cover calibrations with even lower measurement uncertainty and more precisely defined ambient conditions.


As a manufacturer, we naturally have the additional advantage of being able to repair and adjust the devices if necessary and thus achieve optimum accuracy. In addition, well-founded interpretations of the measurement results as well as estimates regarding the definition of extended calibration intervals can also be requested.



Request your Calibration

We currently offer ISO 17025 calibrations for the following instruments:





This offer is continuously extended by other devices and measurement units. When it comes to calibrations which we are not yet able to carry out in-house, we cooperate with suitable laboratories and then we check their results afterwards.


Upon request, we also offer more specific and complex measurements such as calibrating partial discharge calibrators or high-precision multiphase power measurements.
