Differential Thermal Analyzer
The Differential Thermal Analyzer (DTA/DSC) is a high-precision instrument designed to measure thermal effects related to physical and chemical changes of materials. It can determine melting points, heat of fusion, crystallization heat, phase transition heat, glass transition temperature, oxidation induction period (OIT), and thermal stability. The instrument integrates advanced furnace control, precise thermocouple measurement, and user-friendly software, making it suitable for research, quality control, and material development in laboratories and production environments.
Application
The DTA/DSC is applicable to:
Polymers and plastics — analysis of thermal transitions and stability.
Pharmaceutical compounds — melting point, crystallization, and thermal stability studies.
Metals and alloys — phase transformations and heat effect measurements.
Ceramics and composites — thermal stability and reaction heat studies.
Food and chemical materials — thermal analysis and degradation studies.
Materials requiring oxidation induction period (OIT) testing or steam-assisted experiments.
Suitable for laboratories, research centers, and quality control environments requiring precise thermal characterization.
