Structural features:

1. The box body of the high and low temperature alternating humidity test chamber is processed and formed by CNC machine tools, with a beautiful and generous shape, and adopts a non reactive handle for easy operation.

2. The inner box adopts imported high-grade stainless steel (SUS304) mirror panel, and the outer box adopts (SUS304) brushed stainless steel plate or high-quality cold-rolled steel plate spray painted, which increases the appearance texture and cleanliness.

3. Equipped with a large observation window and lighting fixtures to keep the inside of the box bright, and using tempered glass embedded in the heating body, the condition inside the box can be observed clearly at any time.

4. The left side of the box is equipped with a test hole with a diameter of 50mm or 100mm, which can be used for external testing power or signal lines.

5. The insulation material adopts high-density glass fiber cotton with a thickness of 80-100mm. A double-layer high tensile sealing strip that is resistant to high and low temperatures is used between the door and the box to ensure the sealing of the testing area.

6. Equipped with an independent temperature limit alarm system, exceeding the limit temperature and automatically interrupting operation ensures safe testing without accidents.

7. The water replenishment tank is placed at the bottom right of the control box and has automatic water shortage protection, making it more convenient for the operator to replenish the water source.

8. Separating the humidification system pipeline from the control circuit board can prevent malfunctions caused by water leakage in the humidification pipeline and improve safety.

9. The waterway system pipeline circuit system adopts a door opening, which is convenient for maintenance and inspection.

10. The bottom of the test chamber adopts high-quality fixed PU movable wheels.
