Do's and don'ts operating Dry Blocks for temperature calibration.

Making temperature calibration by comparison using a dry block is not at all rocket science and should be perceived a simple and straight forward operation. But there are in fact lots of things that can go wrong providing you with false results compromising your calibration – and even worse your production.

With the current technology, dry blocks are now so advanced and can outperform most other alternatives provided they are operated according to best practices. But remember that an accurate Ellab dry block model RTC159A that offers a stability of +/- 0.03 °C and a high-quality temperature standard with accuracy of +/- 0.02 °C like the Ellab ETS20 can suddenly turn into a calibration system offering a total uncertainty of several degrees, if not used properly.

I have put a paper together which will hopefully give you enough insight to avoid the most basic problems and overcome most of the challenges associated with using dry blocks for temperature calibration.
