Secondary Thermal Analyzer

Product Features:

1. 10-inch color touch screen for perfect online monitoring;

2. Simple operation, one-button sample analysis;

3. Semiconductor cooling, no liquid hydrogen required (cold trap temperature down to -35℃);

4. Real-time display of cycle time for each working state;

5. Sample volume can be adjusted by adjusting the injection time for different sample concentrations;

6. Real-time display of set and actual temperatures for each channel;

7. Programmed temperature ramping: 8 stages, programmable;

8. Sample injection and data acquisition run synchronously, greatly reducing timing errors;

9. Sampling, adsorption, desorption, injection, and backflush cleaning are fully automatic;

10. All pipelines use inert treatment technology;

11. Multiple methods can be stored for easy recall, enabling quick startup and analysis;

12. System leak detection function;
