All calibrators are produced from quality components by skilled staff.
Each calibrator passes several tests during assembly and undergoes
a final inspection and test following a special calibration procedure
laid down by our technical staff.
Caution…
If you decide to check and/or re-calibrate the calibrator, you
must always use certified test equipment only and ensure
proper contact between the test probe and the well of the
calibrator.
Operating guidelines and technical specifications are outlined in the
reference manual order no. 123198 for CTC instruments and in the
user manual order no. 105337 for MTC instruments. Please note that
these are only available in English.
