1. The embedded system is composed of intelligent MCU, which has simple structure, reliable performance and strong anti-interference ability.

2. The test steps such as water discharge, water level setting, stirring, ignition, temperature collection, calibration, calculation and printing are completed automatically, which avoids human error and improves the accuracy and precision.

3. Supports two ignition methods: fuse and cotton thread

4. The chassis features a water level indicator, allowing real-time monitoring of the inner cylinder's water level.

5. The ignition voltage and ignition current can be observed at any time outside the chassis.

6. No need to weigh water and adjust water temperature, reduce the work intensity, improve the measurement accuracy.

7. It features a 7-inch color LCD screen with an integrated mounting design for enhanced stability. The device can be operated directly without requiring an external computer.

8. The instrument automatically announces the results after the experiment.

9. The instrument is controlled by a high-grade imported single-chip microcomputer system and the original imported stirring motor is used, which has the advantages of uniform speed, stable performance, reliable and strong anti-interference ability.

10. The unique calibration technique is adopted to make the instrument more tolerant to the environment, which can improve the accuracy of the test and ensure the stability of the instrument during the long time operation.

11. With the full Chinese menu interface, users only need to load the oxygen bomb to complete the entire experiment. The interface is intuitive, user-friendly, and easy to learn and use. The results are clear at a glance, and the operation is simpler and more humanized.

12. The instrument can display the ignition voltage and ignition current automatically and has the function of automatic diagnosis.

13. The instrument can measure the lower calorific value of the substance, the calorific value and weight of the additives input automatically calculated.

14. The process is automatically controlled to reduce human error. The printing cylinder, dry base high position, analysis base high position, analysis base low position, and received base heat value are measured.
