Calculating Total Uncertainty of Temperature Calibration With a Dry Block

Jan. 11, 2012
In Calibration World magazine (Spring/Summer 2011) there was an article on temperature and the calibration of temperature instruments. In this article we continue with temperature-related articles. 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.

Let's have a look at the various uncertainty components that are related to temperature calibration done using a dry block. These components are relevant to all manufacturers' dry blocks. Some manufacturers specify these components and some do not.

It is possible to use a dry block with the block's internal measurement as the reference (true value), or you can also use an external reference temperature probe inserted in the block as a reference measurement.
