1. Multiple heating tubes heat from all four sides, ensuring rapid temperature rise and strong heat output.
2. Once the set safety temperature is exceeded, the heating system is automatically shut off, providing a high safety factor.
3. The mechanical vacuum gauge is shockproof and anti-magnetic, and is durable.
4. High-temperature resistant sealing strips maintain the vacuum inside the box and effectively prevent air leakage.
5. Both galvanized and stainless steel inner tanks are available, suitable for various scenarios.

Precautions for the use of vacuum drying oven:
1. The oven shell must be effectively grounded to ensure safe use.
2. Before use, check whether the equipment is damaged or abnormal, such as damaged wires and malfunctioning switches.
3. Ensure that the door seal ring is intact and has good sealing performance to avoid vacuum leakage, which may affect the drying effect and the safe operation of the equipment.
4. Ensure that the power supply voltage matches the requirements of the equipment.
5. Do not put flammable and explosive items.
6. The ambient temperature should be between 5°C and 40°C. Avoid direct sunlight or direct radiation from other heat sources. No flammable and explosive items should be placed around it.
7. Do not place items too crowded in the oven. Space must be left to facilitate the circulation of hot air.
8. Do not exceed the maximum load capacity of the drying oven to avoid affecting the heating efficiency and the service life of the equipment.
9. Set the temperature and vacuum degree reasonably according to the drying requirements of the items and the performance of the equipment to avoid affecting the drying effect.
10. When evacuating, close the heating switch first. After the vacuum degree meets the requirements, then turn on the heating switch.
11. During the drying process, regularly check the drying condition of the items to avoid over-drying. Do not run the drying oven for a long time without supervision to prevent accidents.
12. After the drying is completed, do not open the oven door immediately. Let the temperature of the items and the temperature inside the oven drop naturally to prevent the sudden change in temperature from affecting the items.
13. Turn off the power supply after use.
14. After the sample cools, slowly open the vacuum valve to gradually restore the pressure inside the oven to normal pressure, and then open the oven door to take out the sample.
15. Turn off the power supply after use.
16. Clean the drying oven regularly to keep it dry inside and avoid rust and pollution.
17. Regularly inspect and maintain components such as vacuum pumps and heaters to ensure their normal operation.
