Xrw-300a oxidation induction time tester
Product iNToduction:
The oxidative induction time tester is a professional equipment for measuring the oxidation and induction period of materials under the coNTol temperature.
It can be used to automatically record the tube materials and materials in the atmosphere of nitrogen heating with constant speed. When the temperature is reached, the atmosphere switches to the same velocity of oxygen.
After that, the sample is constant at that temperature until the oxidation reaction occurs on the heat curve.
The time interval from the beginning of the flow of oxygen to the oxidation time interval is the oxidation induction period.
The temperature and time curve of oxidation induction period can be recorded automatically, and the temperature difference and temperature relationship between the matter and the reference material can be measured.
The automatic recording describes the temperature (delta T) between the sample and the reference object with temperature or time.
Can also detect phase transition, melt, the change of crystalline structure, boiling, distillation, evaporation and dehydrogenation reaction, fracture or decomposition reaction, oxidation and reduction reaction, the destruction of the lattice structure and other chemical reactions.
Technical parameters:
Scope: 1. The temperature at room temperature to 500 ℃
2. Range of range: 0 ~ plus or minus 2000 mu V
3. DTA accuracy: plus or minus 0.1 mu V
4. The heating rate: 1 ~ 60 ℃ / min
5. The temperature resolution: 0.1 ℃
6. The temperature accuracy: plus or minus 0.1 ℃
7. Temperature repeatability: plus or minus 0.1 ℃
8. Temperature coNTol: temperature rise: program coNTol can be adjusted according to need
Cooling: air-cooled program coNTol * optional semiconductor cooling system, liquid nitrogen cooling system, etc
Constant temperature: the program coNTols the constant temperature time arbitrary setting
9. Furnace structure: the furnace body adopts the open-cover structure, replacing the traditional lifting furnace body with high precision and easy operation
10. Atmosphere coNTol: (optional) gas flowmeter, atmosphere conversion device
11. Data interface: rs-232 serial communication supporting data line and operating software
12. The host display: the large-screen LCD of Chinese character display blue background white word
13. Parameter standard: equipped with standard, the user can correct the temperature
14. Baseline adjustment: the baseline will be adjusted by the baseline slope and intercept
15. Work power: AC 220V 50Hz
