Every balancing machine is a measuring system and must be inspected regularly. With our certification service, we ensure that your calibration rotors, master rotors and test weights are within required specification and tolerance. This means that you can always rely on the precision of your balancing machine.
In November 2021, Hofmann received the accreditation status according to DIN EN ISO / IEC 17025: 2018 for the measurement of master rotors and test masses from the German Accreditation Service (DAkkS) (Download Certificate).
The advantages for our customers are as following:
Hofmann owns a DAkkS (German instiute for ISO/IEC 17025 standard) calibrated 3D-CCM machine from Wenzel with a accuracy of 1.6 µm, an air-conditioned measuring room (class 2) and several DAkkS calibrated scales. The measuring staff is trained according to AUKOM standards with long term experience. All processes are described in a quality handbook.
Hofmann is offering their expertise for calibration of your test rotors, weights or even other 3D measurements.
