The Additel ADT875-155-NO-220V Dry Well Calibrator with No Insert, -40°C to 155°C, 220V combines excellent performance in stability, radial and axial uniformity, and loading with speed, ruggedness and portability.

Self-Calibration

Using an external reference probe as your standard is the best way to perform your temperature calibration. But this method is not always necessary or convenient and depending on the application, using the internal control sensor would be preferred. Traditionally, the internal control sensor has a wide accuracy which can largely be contributed to its long-term drift. The ADT875-155-NO-220V has a built-in self-calibration feature allowing you to run an automated calibration of the internal control sensor using your external reference. With literally a few selections the calibration will run automatically giving you a fresh, traceable calibration of the control sensor which will improve its accuracy as you will not have to account for its long term drift when used as the reference.
