main features 
1. Five-sided heating design
Uniform heating: By heating the sample through all five surfaces (front, back, left, right, and bottom) simultaneously, it ensures that the sample is evenly heated throughout the entire chamber, reducing temperature differences.
Efficient heating element: Using high-density silicon molybdenum or resistance wire as the heating element, it can operate stably at high temperatures up to 1200℃ and provide efficient heating performance.
2. Precise temperature control
PID temperature control system: Utilizing an advanced PID (Proportional-Integral-Derivative) controller to ensure precision and stability in temperature control.
High-precision sensor: Equipped with a high-precision temperature sensor, it monitors temperature changes inside the furnace in real time, ensuring stable and reliable process conditions.
3. High-temperature resistant materials
Furnace chamber material: High-purity alumina fiber is commonly used as the material for the furnace chamber, which exhibits excellent thermal insulation properties and chemical stability, enabling it to operate stably for extended periods at high temperatures.
Refractory layer: Multi-layer refractory material design effectively reduces heat loss and enhances heating efficiency.
3. Automation and intelligence
Programming control: It supports setting parameters such as heating paths and cooling rates through a computer or touchscreen interface, simplifying the operation process and enhancing automation levels.
Data recording and analysis: It can automatically record key operational data and generate reports, facilitating subsequent analysis and improvement.
Remote monitoring: Supports remote monitoring and management through the network, allowing maintenance personnel to keep track of equipment status at any time.
4. Exhaust gas treatment device (design of the second heating chamber)
Temperature elevation: The second heating chamber is used to further elevate the temperature of the exhaust gas, enabling most toxic and harmful gases to decompose into non-polluting gases at high temperatures.
High-temperature treatment: By controlling the temperature of the second heating chamber, it is ensured that the exhaust gas entering it can be fully burned or decomposed, reducing the emission of harmful substances.
