Laboratory guide: How to perform temperature measurements using Type K thermocouples and Fluke Helios Plus 2287A datalogger

Temperature measurements with thermocouples are often used in the field of building physics to measure the temperature distribution in building materials, measure air temperature in ducts or window cavities, etc., and it is, therefore, important to have a good understanding of how to conduct measurements properly to get precise results.
The aim of this Lecture Note is to detail the practical procedure of using type K thermocouples with a Helios Fluke 2287A datalogger, and a compensation box system at Aalborg University, Department of the Built Environment (https://www.en.build.aau.dk/). Furthermore, it will also serve as a guide for preparing and executing calibration for thermocouples.
This Lecture Note will explain how to set up the entire measurement procedure, background information for the different components, and how to prepare it for calibration. The calibration procedure and the equipment involved are also explained.
