Calculating total uncertainty of temperature calibration with a dry block

In this white paper, we will discuss the various uncertainty components related to temperature calibration using a temperature dry-block. Also, we will discuss how to calculate the total uncertainty of a calibration performed with a dry block.

First, let’s discuss what a temperature dry block is. It consists of a heatable and/or coolable metallic block, controller, an internal control sensor and optional readout for external reference sensor. This article will focus on models that use interchangeable metallic multi-hole inserts.

There are fast and lightweight dry blocks for industrial field use, as well as models that deliver near bath-level stability in laboratory use…
