BAXIT DTA differential thermal analyzer
Overview:
Differential thermal analyzer is a technique to measure the temperature difference between a substance and a reference substance under a programmed temperature control. In the DTA test, the change of sample temperature is caused by the endothermic or exothermic effects of the phase transition or reaction.
Standard:
GB/T 19466.2-2004 / ISO 11357-2: 1999 Part 2: Determination of glass transition temperature;
GB/T 19466.3-2004 / ISO 11357-3: 1999 Part 3: Determination of melting and crystallization temperature and enthalpy;
GB/T 19466.6-2009/ISO 11357-3:1999 Part 6 Oxidation induction period Determination of oxidation induction time (isothermal OIT) and oxidation induction temperature (dynamic OIT).
Technical characteristics:
1. Greatly improving the sensitivity and resolution as well as better baseline stability by new fully closed advanced ceramic furnace design structure.
2. High sensor sensitivity, imported alloy sensor, more corrosion resistance, oxidation resistance.
3. Cortex-m3 kernel ARM controller is used for faster computation and more accurate temperature control.
4. USB two-way communication is adopted to fully realize intelligent operation.
5. Use the 7-inch 24-bit color full-color LCD touch screen to display the status and data of the instrument in real time.
6. Software can realize a variety of data processing, such as calculation of enthalpy, glass transition temperature, oxidation induction period, melting point and crystallization of substances, and so on. Intelligent software design, automatic drawing of the instrument in the whole process,
