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 ...
moreIn temperature calibration, what is an axial gradient?
An axial gradient is the temperature difference, or temperature gradient, from the bottom (maximum immersion depth) to the top (surface of the calibrator).
