4、 Conclusion Structure:

4.1.The box is made of high-quality cold-rolled steel plate, coated with electrostatic powder coating on the surface, which is hard and firm, and has * anti rust ability.

4.2.The studio is made of high-quality stainless steel plates, with rounded corners, smooth, fluent, and easy to clean.

4.3.Fill the space between the box and the studio with ultra-fine glass wool insulation material.

4.4.The box door is a double-layer tempered glass structure, which allows clear observation of the items inside the box.

4.5.A rubber sealing ring is installed between the studio and the glass door to ensure a high degree of vacuum inside the box.

4.6.The vacuum gauge is a digital display, which can be manually started, stopped, and decompressed.

4.7.4-liter vacuum pump with a power of 550W.

5、 Product installation and debugging:

5.1.Be careful not to exert force on the glass or collide with the box during transportation.

5.2.After landing, this device should be placed steadily. If the ground is uneven, it should be corrected.

5.3.Please do not use the instrument in places with direct sunlight or high temperature and humidity.

5.4.This device should be kept away from electromagnetic interference sources and the grounding wire of the device should be effectively grounded.

5.5.When this device is running normally, the items inside the box should not touch the inner wall.

5.6.Do not place the power cord close to the back, and do not let instruments or other objects press on the power cord to avoid damaging it.
