1. Temperature control and accuracy
Temperature control range: Ensure that the maximum temperature of the resistance furnace can reach 1200 ℃, with a certain margin (such as 1250 ℃) to cope with fluctuations in actual use.
Temperature control accuracy: Select the appropriate temperature control accuracy (such as ± 1 ℃, ± 5 ℃) according to experimental or production requirements. High precision temperature control is suitable for temperature sensitive material processing.
Temperature uniformity: Check whether the temperature distribution inside the furnace is uniform to avoid excessive local temperature differences affecting the experimental results.

2. Furnace material and structure
Material selection: The furnace should be made of materials that are resistant to high temperatures and corrosion, such as ceramic fibers, alumina, or silicon carbide. These materials can withstand high temperatures of 1200 ℃ and have good insulation properties.
Structural design: The furnace should be designed reasonably to avoid cracking caused by rapid cooling and heating. At the same time, the size of the furnace should match the actual usage requirements, ensuring heating efficiency and avoiding space waste.

3. Heating element
Type selection: Common heating elements include resistance wires, silicon carbide rods, and silicon molybdenum rods. For high temperatures of 1200 ℃, silicon carbon rods or silicon molybdenum rods are more suitable because they have higher temperature resistance and oxidation resistance.
Durability: Heating elements should have good thermal shock resistance and long lifespan, reducing replacement frequency and maintenance costs.

4. Safety performance
Over temperature protection: The equipment should be equipped with over temperature alarm and automatic power-off function to prevent damage to the equipment or safety accidents caused by excessive temperature.
Leakage protection: Ensure that the resistance furnace has good grounding and leakage protection devices to ensure the safety of operators.
Furnace door safety: The furnace door should be designed with a safety lock or limit device to prevent accidental opening during the heating process.

5. Equipment structure and operation
Furnace structure: The box type resistance furnace should have good sealing and insulation performance, reduce heat loss, and improve energy efficiency.
Convenience of operation: The device should be equipped with an intuitive control panel and interface for setting parameters such as temperature and time.
Maintenance convenience: The furnace and heating elements should be easy to disassemble and replace, facilitating daily maintenance and upkeep.

6. Energy consumption and efficiency
Energy Efficiency Ratio: Choosing equipment with low energy consumption and high thermal efficiency can save costs for long-term use.
Heating speed: Select the appropriate heating power according to actual needs to ensure that the equipment can quickly reach the set temperature.

7. After sales service and brand
Brand reputation: Choosing products from well-known brands usually ensures better quality and after-sales service.
After sales service: Ensure that the manufacturer can provide timely technical support and maintenance services to avoid equipment failures affecting production or experimental progress.
