Instrument introduction:
Differential scanning calorimetry, as a classical thermal analysis method, has been widely used in the research and development, process optimization, quality control and failure analysis of various materials and chemistry fields. By using DSC, we can study the phase transformation of inorganic materials, melting of polymer materials, crystallization process, polymorphism of drugs, solid / liquid phase ratio of oil and other foods.
Instrument purpose：
Measure the physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transition reaction heat, thermal stability of products, curing / crosslinking, oxidation induction period, etc.
Main features：
1. The new fully enclosed metal furnace design structure greatly improves sensitivity, resolution and baseline stability.
2. It adopts imported alloy sensor, which is more corrosion-resistant, anti-oxidation and high sensitivity.
3. With Cortex-M3 core arm controller, the operation speed is faster and the temperature control is more accurate.
4. USB two-way communication is adopted to realize intelligent operation.
5. The 7-inch 24 bit color full-color LCD touch screen is used to display the status and data of the instrument in real time.
