DAkkS Calibration of Dry Block Calibrators
Dry-block calibrators are calibrated by comparison with calibrated resistance thermometers or thermocouples. The calibration is based on the DAkkS-DKD guideline R5-4 for calibrating block calibrators or Klasmeier’s own test reports for ISOTECH devices. The calibration is provided with a DAkkS calibration certificate as standard, but traceable calibration can also be done.
- Wide temperature range: -40 °C to 1300 °C
- Short turnaround time of 3-5 working days
- Manufacturer independent calibration
- Possibility to optimise your temperature dry block calibrator by manufacturing custom-built calibration inserts and ceramics

When calibrating dry-block calibrators, the temperature difference between the setpoint and the calibration temperature is not of essential importance, as the calibration only determines an actual state. However, many customers consider this temperature difference to be of particular importance, as they use the block calibrators in order to be able to make conformity statements about their test items. However, as block calibrators are often heavily used, this is often difficult due to the drift of the instrument. The calibration service Klasmeier has developed its own optimization procedure to improve the “control and display accuracy”. ISOTECH calibrators calibrated at Klasmeier go through an optimization cycle several times. This is an approximation procedure in which the control parameters are increasingly better adapted to the calibration temperature. For third-party devices, optimization is possible if the corresponding procedure is provided.
