BROCKHAUS certified reference sample

The quality requirements for hard and soft magnetic materials are constantly increasing. Therefore, quality controls are becoming more and more important both during production and further processing. In addition to the development, production and marketing of hard and soft magnetic measuring instruments, we therefore offer the service for contract measurements of sample material in our measuring laboratory.

You should take the benefit from having your Epstein and Sheet Samples (500 x 500 mm) calibrated according to international standards in our calibration laboratory and using them as a reference for your application. Use this opportunity and get your reference samples calibrated in our laboratory DAkkS-accredited acc. to DIN EN ISO/IEC 17025:2018.

To ensure the comparability of the test results, it is necessary to calibrate the measuring systems according to internationally recognized standards. The basis for all calibrations of the hard and soft magnetic BROCKHAUS measuring systems are the measurements of the international SI units voltage, current and frequency as well as nuclear magnetic resonance.

BROCKHAUS meets these increasing demands on test equipment by continuously and gradually revising existing measuring systems and developing new measuring methods.
