Shielding protection of signal acquisition circuit, strong anti-interference, high Baseline stability. The instrument is Touchscreen type, which can perform Glass transition temperature test, phase transition test, melting and thermal enthalpy test, product stability, curing, oxidation induction period test, oxidation induction temperature, etc., with a wide range of applications.
Features
1. Industrial-grade 7-inch Touchscreen, displaying rich information.
2. New metal furnace structure, Baseline better, higher accuracy. Heating indirect conduction mode, high uniformity and stability, reduce pulse radiation, better than the traditional heating mode.
3. USB communication interface, strong versatility, reliable and uninterrupted communication, supports self-recovery connection function.
4. Automatically switch two channels of atmosphere flow, fast switching speed and short stabilization time. At the same time, increase one protective gas input.
5. The software is simple and easy to operate.
Principle
The oxidation induction time (OIT) is measured by DSC. The sample is usually heated to a specified temperature and thermostatic in a nitrogen atmosphere, and then switched to an oxygen atmosphere. After a period of time, the material begins to oxidize and releases heat. This released heat is detected by the Sensor, and through software analysis, the oxidation induction time (OIT) is obtained. The length of the oxidation induction time is a parameter of the resistance of the reactive material to oxidation analysis. The melting point is the temperature at which a solid changes its state from a solid state or melts into a liquid state. Mixtures of multiple components also produce peaks; the test of thermal enthalpy value is also suitable for the test and analysis of crystallinity.
Applications
Glass transition temperature test, phase transition test, melting and enthalpy test, product stability, curing, oxidation induction period test, oxidation induction temperature
Standards
GB/T 33466.1-2016、GB/T 40271-2021、GB/T 41928-2022、GB/T 19466.1-2004、GB/T 19466.4-2016、GB/T 19466.5-2022、GB/T 19466.2-2004、GB/T 19466.3-2004
Steps
1. The specimen is heated to a specified temperature under a nitrogen atmosphere and is thermostatic.
2. Switch to an oxygen atmosphere.
3. The material begins to oxidize and releases heat, and the Sensor detects the released heat.
4. Through software analysis, the induction oxidation time (OIT) is obtained.
5. Users can use their own reference materials (indium, tin) to correct the temperature.
Notice
• Power Supply is AC220V/50Hz or customized, make sure the power supply matches.
The gas flow range is 0-200mL/min, and the gas pressure should be less than or equal to 0.5MPa.
• The instrument automatically switches between nitrogen and oxygen atmospheres, and attention should be paid to gas switching during operation.
Equipped with standard materials (indium, tin), users can adjust the temperature by themselves to ensure test accuracy.
