One Click AutoEvaluation for Dilatometer Signals (dL) Improved

AutoEvaluation is an intelligent software algorithm and part of the NETZSCH Proteus® software, which automatically and autonomously evaluates thermo-analytical measurement curves. It has already been introduced and successfully applied for Differential Scanning Calorimetry and Thermogravimetric Analysis and is also available for dL signals as generated by dilatometers (DIL) and thermomechanical analyzers (TMA). As an improvement, the mean CTE (Coefficient of Thermal Expansion) values are evaluated additionally before and after the glass transition.
