Calibration of KERN scales, balances and test weights

Calibration of Balances, Weights and Force Measurement Devices

kern dkd certificates

The KERN DKD calibration laboratory (DKD-K-11801) for electronic balances, test weights and force measurement devices has been accredited by DKD since 1994 and today is one of the most modern and best-equipped DKD calibration laboratories in the world for these measurement values.
Thanks to the extremely high level of automation, we are in a position to carry out DKD calibration of non-automatic electronic balances, test weights and force-measuring devices, round the clock.

The principle

Every electronic measuring device will only give correct results if it is checked regularly, i.e. calibrated correctly and adjusted when required. An electronic balance, test weight or another measuring device is only a reliable measuring and checking tool if it is calibrated and this calibration is documented as part of a quality procedure. DKD calibration (DKD = German calibration service) documents traceability to the national standard and this then meets the standard requirements of QM systems. DKD calibrations are valid internationally.

Calibration of measuring devices

Measuring “correctly” is of elementary significance, as it is not unusual for inaccurate or “wrong” measurements to have expensive economic consequences. Calibration or establishing the accuracy of checking equipment is carried out by accredited laboratories throughout the world in accordance with the DIN EN ISO/EIC 17025 standard. On an international level, the EA (European Co-operation for Accreditation) and ILAC (International Laboratory Accreditation Cooperation) monitor the upholding of the highest quality standards. In Germany this is carried out by DAkkS (German accreditation point).

What does calibration mean?

Determining and documenting the deviation from true, actual measure value of the value displayed by a measuring device or of the value given by checking equipment.
When should you carry out DKD calibration?
DKD calibration is always necessary, when checking equipment is to be used in a QM process (e.g. in accordance with ISO 9000ff, TS 16949, VDA, FDA, GLP, GMP, …).  The operator controls the use of checking equipment and periodic recalibration time intervals themselves. DKD calibration certificates are recognised internationally.

Deutsche Akkreditierungsstelle (DAkkS)

(German accreditation agency)
On the basis of EC regulation no. 765/2008, the accreditation point of the German calibration service (DKD) was transferred to the German accreditation point (DAkkS) with effect from 17.12.2009. Within DAkkS, this forms the Metrology department. 

Who needs a DKD calibration certificate?

In the context of standard requirements for monitoring checking equipment, every company with a Quality Management system is obliged to test and document its measuring equipment at regular intervals. A DKD calibration certificate fulfils this obligation.  See

The KERN calibration laboratory (DKD-K-11801)

KERN has a highly-automated DKD laboratory with accreditation to DIN EN ISO/IEC 17025 in the field of balances, test weights and force measurement. By using the most modern calibration technology with high-end calibration robots in fully air-conditioned laboratories, the measurement uncertainty and process times are reduced to a minimum, and also the quality of the calibration is increased. As an accredited and certified calibration service provider with decades of experience, we offer you an extensive range of services, which will leave no demand unfulfilled.
