Performance characteristics:

1. The oxygen bomb adopts an automatic lifting system, which automatically fills and deflates oxygen, and automatically detects the oxygen filling pressure.

2. Advanced refrigeration technology ensures that the temperature difference between the inside and outside of the instrument meets the requirements of the national standard and can work continuously for 24 hours.

3. It is controlled by computer fully automatic software, which can automatically identify the oxygen bomb and complete all testing work automatically.

4. Stainless steel vacuum inner barrel. The mixing system adopts imported motor with more stable performance.

5. Fast test speed, test cycle ≤ 8 min (fast method) ≤ 15 min (GB/T213-2008)

6. Thermal capacity stability ＜ 0.2%, precision ＜ 0.1%, temperature resolution 0.0001K

7. The product is easy to have good performance and reliability even under harsh environment.

8. Compact structure, beautiful appearance, easy installation and maintenance, low failure rate.

9. Small size, large amount of mold manufacturing, high precision.

10. The repeatability and reproducibility of the calorific value test are superior to the requirements of the national standard GB/T212-2008.

11. High degree of automation, automatic use of the built-in fixed container to determine the water volume of the inner barrel, automatic control of the temperature difference between the inside and outside of the instrument, and automatic completion of the whole process of the experiment.

12. The WIN7 operating system is adopted to realize multiple control of one computer. The mutual test does not affect each other, and the software runs stably.

13. The data processing function is rich, and users can easily query historical experimental data, data of the day, parallel sample data, etc.

14. The electronic balance can be connected to realize automatic input of sample weight.
