4. Capable of querying historical curves and automatically determining temperature equilibrium;

5. Safe and reliable testing process with convenient operation;

6. Custom-made molded refractory furnace chamber with excellent thermal insulation;

7. Equipped with high-quality strip heaters, allowing furnace temperature to reach 900°C;

8. Uses CH341 system-driven professional software to display real-time furnace temperature, sample center temperature, and sample surface temperature curves, enabling automatic control, data acquisition and processing, data storage, and output of test results;

9. Top-mounted observation mirror for safe viewing of sample combustion status inside the furnace.
