Working Principle

The DSC-200 operates based on the principle of Differential Scanning Calorimetry (DSC). During a controlled heating or cooling program, it measures the difference in heat flow between a sample and a reference under the same temperature conditions.

When a material undergoes thermal transitions, such as melting, crystallization, glass transition, or curing, its heat absorption or release changes. The instrument detects these thermal effects and generates a DSC curve showing heat flow as a function of temperature or time.

By analyzing the resulting curve, users can determine characteristic thermal parameters, including transition temperatures, melting and crystallization behavior, curing characteristics, and oxidation induction properties. Both heating and cooling scans provide a more complete understanding of material thermal behavior.
