7. Calibration services
DKD-certificates - other certificates:
If device should be certificated for its accuracy, it is the best
solution to return it with the referring sensors to the manufacturer.
Only the manufacturer is capable to do efficient recalibration if
necessary to get results of highest accuracy!
