Dry-well calibrators have become the most practical tools in industrial temperature calibration. They now build units that fit into the palm of your hand that is accurate enough to lab standards. Each unit is unique in its ability to satisfy the requirements of specific calibration applications. Which is why it is important when choosing one to find the option that best fits your needs. Here is a guide to finding a good match for your application.
A dry-block calibrator also known as a dry-well calibrator is used inaccurate, liquid-free calibrations of temperature devices. A dry block or dry-well features a heated block which contained a temperature-controlling sensor.
If you are series about portable temperature calibration tools, then you understand that a good dry-well calibrator is more than just a stable heat source.
When choosing a dry well calibrator, there are key factors to consider.
Traditionally, an internal control sensor has a wide accuracy, which largely contributes to its long-term drift. This is why using an external reference probe as your standard is the best way to perform a temperature calibration. However, it is not always necessary or convenient depending upon the application, which is why an internal sensor would be preferred.
Using a dry-well calibrator with a built-in self-calibration feature allows you to run an automated calibration of the internal control sensor using your external reference. The calibration can 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 a reference.
Select the dry-well that best fits your application, and you will have years of successful calibrating. The Additel 875 Series Dry-Well Calibrators offer three models so that you can choose the perfect one for your needs.
