In temperature calibration, what is a radial gradient?
A radial gradient is the temperature difference between the individual bores of an insert of a dry well calibrator (portable temperature calibrator).
For the insert of a dry well calibrator, how large should the bore diameter be?
The diameter of a test item determines the size of the drilled bore. The bore diameter should be as small as possible after taking into account the thermal expansion of the test item. This is because the air gap between the thermometer and the bore ...
