1. Temperature range and accuracy
Maximum temperature: Determine the required maximum temperature based on experimental or production requirements. For example, some high-temperature experiments may require temperatures of 1600 ℃ or even higher, while some conventional heat treatments may meet the requirements at around 1200 ℃.
Temperature control accuracy: Temperature control accuracy directly affects the reliability of experimental or production results. Choose a box furnace with high-precision temperature control function, such as using PID regulation, self-tuning function, etc. The temperature control accuracy can usually reach ± 1 ℃ or even higher.

2. Furnace size and volume
Furnace size: Select the appropriate furnace size based on the size and quantity of the sample. For example, for small samples, a smaller furnace size is sufficient to meet the requirements; For batch processing or large samples, it is necessary to choose a box furnace with a larger volume.
Volume: Volume not only affects the processing capacity of the sample, but also relates to the uniformity and stability of the atmosphere inside the furnace. Generally speaking, the larger the volume, the better the uniformity and stability of the atmosphere inside the furnace.

3. Heating element and heating method
Heating elements: Common heating elements include silicon molybdenum rods, resistance wires, etc. Different heating elements have different performance characteristics such as service life and heating rate. For example, silicon molybdenum rods have the advantages of high temperature stability and long lifespan, making them suitable for high-temperature experiments.
Heating methods: The heating methods of box furnaces mainly include resistance heating and radiation heating. Resistance heating heats evenly, but the heating rate is slow; Radiation heating is suitable for rapid heating, but uneven temperature distribution may occur. Choose the appropriate heating method based on experimental or production needs.

4. Atmosphere control ability
Argon gas supply function: Ensure that the box furnace has the function of supplying argon gas and can accurately control the flow rate and pressure of argon gas. This is important for experiments or production processes that require inert gas protection or reducing atmosphere.
Atmosphere regulation system: Equipped with advanced atmosphere regulation system, it can accurately control gas flow rate, pressure and other parameters, creating a stable and satisfactory atmosphere environment.

5. Security performance
Safety protection device: Choose a box furnace equipped with multiple safety protection devices such as over temperature alarm, break protection, leakage protection, overcurrent protection, pressure protection, etc. These devices can promptly cut off the power and issue an alarm in case of abnormal equipment conditions, ensuring the safety of operators and the normal operation of the equipment.
Gas safety: Ensure that the gas pipelines and valves of the box furnace are strictly designed and tested to prevent safety hazards such as gas leaks.

6. Operational convenience
Temperature control method: Choose a box furnace with programmed temperature control function, which can preset complex heating, insulation, and cooling programs according to different process requirements. This can improve the automation level of the experiment and reduce human operational errors.
Operation interface: The operation interface should be simple and easy to understand, making it convenient for experimental operations. For example, using intuitive display methods such as LED digital instruments or LCD displays.

7. Brand and after-sales service
Brand: Choose reputable brands and suppliers to ensure product quality and reliable after-sales service. Famous brands usually have more comprehensive quality management systems and more professional technical support.
After sales service: Understand the supplier's after-sales service policy, including equipment installation, commissioning, training, maintenance, and upkeep services. Good after-sales service can ensure that the equipment receives timely technical support and maintenance during use.

8. Other considerations
Double layer shell structure: Choosing a box furnace with a double layer shell structure can effectively isolate the heat radiation from the internal high temperature to the external environment, enhancing the overall stability and durability of the furnace body. Meanwhile, the double-layer shell structure also helps to improve the insulation performance of the furnace and reduce heat loss.
Air cooling system: Equipped with an air cooling system can quickly cool down the surface of the furnace, improving the safety and service life of the equipment.
Customized services: customized services based on specific processes and usage scenarios, such as furnace size, shape, heating element layout, power, and control system configuration. This can improve the applicability of the equipment and reduce operating costs.
