KERN DKD<br />

Calibration service for balances<br />

The advantages of using KERN in-house calibration<br />

(you send your balance to us)<br />

To be recommended with new equipment and for balances<br />

which can be transported economically, as the travel<br />

costs for on-site calibration are then not applicable.<br />

The advantages of using KERN on-site calibration<br />

(we visit you)<br />

In Germany, KERN has access to a<br />

comprehensive network of employees<br />

at the KERN DKD calibration laboratory,<br />

who can carry out on-site<br />

calibration of scales up to 6 to. The<br />

calibration service is independent<br />

of the brand.<br />

Preliminary maintenance work by<br />

agreement. Prices for on-site calibration<br />

on request.<br />
