The Oxidation induction time tester (OIT for short) uses differential thermal analysis (DTA) method to test the accelerated aging degree of plastics in high-temperature oxygen. It is to evaluate the material's resistance to heat degradation during molding, storage, welding and use.
Applications
Measure physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transition reaction heat, product thermal stability, solidification/crosslinking, oxidation induction period, etc.
Features
1. Brand new fully enclosed metal furnace body design structure greatly improves the sensitivity and resolution as well as better baseline stability.
2. Imported high sensitivity alloy sensor features better resistant to corrosion and oxidation.
3. Cortex-M3 core ARM controller, faster calculation speed, more accurate temperature control.
4. USB two-way communication, fully realize intelligent operation.
5. 7-inch 24bit color full-color LCD touch screen to display the test status and data in real time.
6. Intelligent software design, automatic drawing of the instrument throughout the process, the software can realize various data processing, such as the calculation of enthalpy, glass transition temperature, oxidation induction period, melting point and crystallization of substances, etc.
