What happens to my stored data?

Data protection is a top priority for us. We guarantee that your data is safe with us and that we do not pass it on to third parties (e.g. our partner Trescal). Thus, the cover sheet with all important customer-related data is created at Hoffmann after the calibration at the service provider.

What search options do I have to identify my measuring device in the digital calibration service?

During the calibration process, we apply a data matrix code (DMC) using a sticker. This simplifies the clear identification of your measuring devices significantly. In addition, you have the possibility to identify your measuring equipment by means of the vendor serial number as well as your customer inventory number. Using the search function in the calibration service, you can easily find specific measuring devices with these characteristics.

Which service provider does Hoffmann work with for calibration services?

Our new calibration laboratory is one of the most modern in Europe. With Trescal, we have a partner on our side that has accredited laboratories worldwide and offers comprehensive knowledge in the field of testing, calibration and repair. Trescal has been a trusted partner in the chemical, pharmaceutical, aerospace, automotive, electronics, electricity and telecommunications industries since 1999. With more than 620 accreditations in 25 metrology disciplines, Trescal has access to a unique portfolio.

What are the differences between works standard calibration and DAkkS calibration?

1. DAkkS - Calibration Certificate Accredited calibration laboratories are connected to the national standards "on a short path" via reference standards. As an independent institution, DAkkS assesses, confirms and monitors the technical competence of these laboratories. By regularly checking the processes and the metrologically correct implementation of the calibration process, you can rely on your measurement results. Through multilateral agreements of the national accreditation bodies, the DAkkS calibration certificates are internationally recognized and valid. This avoids costly multiple accreditations. 2. Works Standard (ISO) Calibration Certificate In contrast to DAkkS calibration, works standard calibration is only traceable to the works standard and not to the national standard. As a result, the factory calibration is not recognized internationally by all operators. Trescal laboratories comply with the standard according to DIN EN ISO/IEC 17025 without exception. This guarantees the traceability of calibrations and samples. Trescal also applies the same standards for a works standard calibration as for a DAkkS calibration.
