1. Temperature range and accuracy
Temperature range: Firstly, determine the maximum temperature of the object to be heated and select a high-temperature box type electric furnace that can cover this temperature range. Different models of electric furnaces have different temperature ranges, some can reach 1700 degrees, while others are suitable for lower temperature ranges.
Temperature control accuracy: For operations that require high-precision heating, temperature control accuracy is an important indicator. Understand and select the temperature control accuracy suitable for the desired operation, for example, the temperature control accuracy may be less than ± 1 ℃ (test point is 1000 ℃).
2. Heating power and speed
Heating power: Select the appropriate heating power according to the volume and heating speed requirements of the object to be heated. The heating power directly affects the heating speed, and high-power electric furnaces usually have faster heating speeds.
Heating speed: Pay attention to the heating and cooling rates of the electric furnace, as these parameters can affect the efficiency of experiments or production. For example, some electric furnaces have a heating rate of ≤ 10 ℃/min within the recommended temperature range, and the fastest heating rate may reach ≤ 30 ℃/min.
3. Safety performance and control functions
Safety performance: Ensure that the high-temperature box type electric furnace has necessary safety performance, such as over temperature protection, short circuit protection, etc., to prevent accidents during equipment use.
Control function: Some additional control functions, such as timing function, program control function, etc., may be very important for users with special needs. These features can improve the flexibility and usability of the device.

4. Equipment size and volume
Size and Capacity: Choose a high-temperature box type electric furnace of appropriate size and capacity according to the size and usage requirements of the location. Ensure that the electric furnace can accommodate the object to be heated and is suitable for the usage environment. For example, furnace size and external dimensions are factors that need to be considered.
5. Material and Construction
Material: Pay attention to the heating elements and furnace body material of the electric furnace. Heating elements such as resistance wires, nickel chromium wires, silicon carbide rods, etc. can affect the heating effect and durability. The material of the furnace body, such as ceramic fibers, affects the insulation effect and high temperature resistance.
Construction: Additional features such as air-cooled system, observation window, and drawer style design can also be considered when choosing. These functions can improve the practicality and convenience of the device.
6. Cost and Brand
Cost: Choose a suitable high-temperature box type electric furnace based on the budget. The prices of electric furnaces of different brands and models vary greatly, and it is necessary to balance them according to actual needs.
Brand: Choosing products from well-known brands usually provides better quality assurance and after-sales service. At the same time, the actual usage effect of the product can be understood by viewing user reviews, consulting sales personnel, and other methods.
7. Other precautions
After sales service: Good after-sales service is one of the important factors to consider when choosing equipment. Ensure that the selected brand or supplier can provide timely and professional after-sales service support.
Actual needs: In the selection process, it is necessary to comprehensively consider the actual needs. The demand for high-temperature box type electric furnaces may vary among different industries and fields, so it is necessary to choose according to specific situations.
