Portable temperature calibrators

Efficient calibration with temperature calibrators from WIKA

Portable temperature calibrators (dry-well calibrators) are electronic controllers which automatically, quickly and dryly supply a temperature. Due to the high reliability, accuracy and simple operation, portable temperature calibrators are particularly suitable as a factory/working standard for the automatic testing and/or calibration of temperature measuring instruments of all types. A major advantage is offered by the large sleeve diameters and the fast, stable temperature control, since, as a result of these characteristics, the time for calibration can be used very effectively.

FAQ

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 ...

What is the minimum immersion depth with dry well calibrators?

The minimum immersion depth for dry well calibrators is driven by the axial gradient, since warm air rises from the bottom of the calibrator. The minimum is usually 2.75 inches (70 mm). If this depth cannot be reached, an external reference thermom ...
