From time to time we get information from end-users of JOFRA dry-block calibrators that something is wrong with the calibrator, as it is not able to meet the temperature specifications.
This is often due to the fact that the customer is using a wrong insertion tube, although he is in good faith.
Therefore, you can save a lot of time and irritations by using the right insertion tube.
Using inserts with the correct size, holes and material
To avoid problems, waste of time and to get the optimum use of your calibrator we recommend that you use inserts from AMETEK Calibration Instruments as they follow our specifications.
AMETEK Calibration Instruments supply undrilled inserts, predrilled insert and multi-hole inserts.
Custom-made special inserts are made on request.
When ordering custom made special inserts a few details have to be noticed:
- Specify the instrument for which the inserts are ordered
- Specify the sensor size for each hole
Please use the order form for special inserts.
