Product Overview
The DTA-1550S Differential Thermal Analyzer is an analytical instrument that measures the relationship between temperature difference and temperature between a substance and a reference material under programmed temperature control. Its differential thermal analysis curve describes the variation of the temperature difference between the sample and the reference material with temperature or time, and can be used to detect endothermic or exothermic effects caused by phase transitions or reactions.

Working Principle
Differential Thermal Analysis (DTA) is a technique that measures the temperature difference between a substance and a reference material as a function of temperature under programmed temperature control. In DTA experiments, changes in sample temperature are caused by endothermic or exothermic effects due to phase transitions or reactions. The DTA curve describes the variation of the temperature difference between the sample and the reference material as a function of temperature or time.
Application Field
Phase transitions, melting, transformation of crystalline structures, boiling, sublimation, evaporation, dehydrogenation reactions, cleavage or decomposition reactions, oxidation or reduction reactions, destruction of lattice structures, and other chemical reactions.
Complies with standards
