2、 Product functional characteristics

1. Adopting a single-chip microcomputer+touch screen control, high-precision temperature gauge independent electronic control system, it solves the problem of achieving the actual conversion accuracy of PLC system's digital to analog while improving anti-interference ability. Using a microcomputer for more precise control.

2. Start, timing, ventilation, lighting, and heating are all implemented on the touch screen; After a set of experiments, the device will automatically pop up for saving, simply edit the save name; All saved data can be queried in historical data.

3. A seven inch color touch screen.

4. Intelligent 7mm limit adjustment.

5. The fixture is suitable for samples of various shapes and sizes.

6. Free movement in the X and Z directions for convenient sample positioning by customers.

7. Adopting one click operation, during the experiment, one button completes the entire process without the need to switch between complex buttons.

8. The sample car adopts a fully enclosed structure and will not overturn.

9. Equipped with a flame height gauge for easy observation of flame height.

10. Over temperature protection.

11. Adopting a red line photoelectric stop switch to make the limit more precise.

12. The controllable silicon temperature control system makes temperature regulation more accurate.

13. Digital display of time and temperature, convenient for observation and recording.
