1. The cold and hot circulation system ensures a more homogeneous temperature, augmenting efficiency and diminishing energy consumption.
2. The high-quality compressor offers vigorous heating and cooling, featuring high efficiency, low energy consumption and an extended service life.
3. The heat-resistant sealing ring possesses excellent sealing performance and effectively prevents temperature dissipation.
4. The intelligent PID temperature control technology guarantees precise temperature control with minor fluctuations. It incorporates various safety protections such as timing, self-diagnosis, power-loss memory and over-temperature self-limitation.
5. The embedded LCD instrument simplifies the operations of timing and temperature control, presenting a high-definition display and energy-saving functionality.
6. The interior is furnished with LED illumination, facilitating the observation of the sample status.
7. It possesses a precise temperature and humidity control system, capable of simulating various environmental conditions to fulfill the requirements of diverse tests.

Precautions:
1. The enclosure of the box must be effectively grounded to ensure safe usage.
2. Before utilization, inspect the equipment for any damages or abnormalities, such as damaged wires or malfunctioning switches.
3. Ensure that the sealing gasket of the box door is intact and has excellent sealing performance to avoid temperature leakage, which might influence the experimental outcomes and the safe operation of the equipment.
4. Verify that the power supply voltage complies with the equipment requirements.
5. Flammable and explosive items must not be placed inside.
6.The ambient temperature shall be maintained within the range of 5°C to 30°C, and the relative humidity shall not exceed 85%. It is necessary to avoid utilization in environments with high temperature, high humidity or extreme temperature variations. When the set temperature is ≤ 10°C, the ambient temperature should not be higher than 26°C.
7. Prevent samples from being placed too densely, which may affect the temperature distribution. Ensure air circulation and uniform temperature.
8. Set the temperature rationally in accordance with the cultivation requirements of the items and the performance of the equipment.
9. During the usage process, try to avoid frequently opening and closing the box door to avoid affecting the stability of the internal temperature.
10. After the usage is completed, turn off the power supply.
11. Regularly clean and disinfect the furnace chamber, maintain internal dryness, and avoid rusting and contamination.
12. Regularly inspect and maintain components such as the temperature control system, temperature sensors, air circulation system, heating and cooling systems, etc., to ensure their normal operation.
