Declaration of conformity

Safe, reliable measurement results thanks to guaranteed legally secure calibration certificates!

  • The declaration of conformity is a certificate for legally compliant calibration certificates
  • And ensures that calibrations are performed by our accredited laboratories
  • The declaration gives you as a user security for the reliability of your measurement results

The declaration of conformity serves as a written confirmation for legally compliant calibration-certificates and assessments. Calibrations of accredited laboratories are giving the user confidence about the reliability of the measurement results, increase the confidence and the comparability of the national and international market and are serving as a measurement basis for the Measurement and Test Equipment Monitoring within the framework of quality assurance.


Why should you have your equipment calibrated by us?

As a group of companies and manufacturer of measuring and testing equipment, we issue a declaration of conformity for our DAkkS certificates. Thus, you receive guaranteed legally compliant calibration certificates.

Both our sister company, Gossen Metrawatt GmbH, as manufacturer and distributor of measuring and test equipment, including a DAkkS calibration certificate for new deliveries, and we, GMC-I Service GmbH, as recalibration laboratory, can issue genuine declarations of conformity.



  • Performing a 100% final inspection according to the manufacturer's specifications before calibration
    A final inspection examines all areas of the technical specifications, not just those documented in the calibration certificate
  • Legal certainty that our product complies with the data - an important point in product liability
  • Completeness of the manufacturer's (Gossen Metrawatt) measurement and product data assured - other calibration laboratories do not necessarily have this data available
  • Knowledge and ability to repair, reconcile, and final test Gossen Metrawatt instruments that have not passed the conformance process
  • We carry out the adjustment of values and "small" maintenance work partly free of charge for you










  • Would you like to find all calibration certificates centrally in one place?
  • And never miss an upcoming calibration again?
  • As well as release open estimates online and in real time?
