The measurement system consists of the sample tube, bearings, and pushrod. Two moveable sample bearings (cutting edges) ensure reliable and frictionless positioning of the sample within the tube. Given the very high temperatures under investigation, considerable care must be taken to prevent chemical or physical interaction between the sample and measurement system. For this reason, several material types are used based on the temperature range of interest and the reactivity of the sample.
