1. The intelligent digital-display PID temperature control instrument has small fluctuations in temperature control accuracy and is endowed with functions such as timing, over-temperature alarm, temperature deviation correction, temperature control self-tuning, power-loss memory, and self-diagnosis of faults.
2. The box is furnished with barred partitions whose spacings are adjustable, enabling smoother air circulation within the box. Moreover, when the partitions are superimposed, the bearing capacity doubles.
3. There are LED lighting strips inside the box, which is a humanized design for intuitive and visible observation of the culture status of the samples.
4. Silicone sealing rings improve the sealing property of the box, and heat is not prone to loss.
5. The surface adopts the electrostatic spray coating process, along with environmentally friendly and heat-insulating materials, making it difficult to get burned.
6. A ventilation valve is equipped at the top, allowing the moisture inside the box to be discharged outside at any time.

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. It is suggested to use under an ambient temperature of below 25℃, and the equipment's operating temperature should be above 45℃ (select a biochemical incubator with refrigeration function if the temperature is below 45℃). Excessive ambient temperature or too low operating temperature can affect the performance, and the equipment temperature might get out of control. The relative humidity should not exceed 85%. Avoid using it in environments with high temperature, high humidity or extreme temperature variations.
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.
