In combination with a DAkkS calibration certificate the best pre-requisite for proper balance calibration. The KERN DAkkS calibration laboratory today is one of the most modern and bestequipped DAkkS calibration laboratories for balances, test weights and force-measurement in Europe. Thanks to the high level of automation, we can carry out DAkkS calibration of balances, test weights and force-measuring devices 24 hours a day, 7 days a week.

Range of services:

• DAkkS calibration of balances with a maximum load of up to 50 t
• DAkkS calibration of weights in the range of 1 mg – 2500 kg
• Volume determination and measuring of magnetic susceptibility (magnetic characteristics ) for test weights
• Database supported management of checking equipment and reminder service · Calibration of force-measuring devices
• DAkkS calibration certificates in the following languages DE, EN, FR, IT, ES, NL, PL
• Conformity evaluation and reverification of balances and test weights
