The walk-in constant temperature and humidity laboratory is suitable for testing various performance indicators of aerospace products, information electronic instruments, materials, electrical engineering, electronic products, and various electronic components in high and low temperature or hot and humid environments.
Structural features
1. The shell of the walk-in constant temperature and humidity test room is made of high-grade high-quality stainless steel (SUS#304) CNC machine tool processing.
2. The inner tank is made of imported high-grade stainless steel (SUS304) mirror panel.
3. Insulation material: high-density fiberglass cotton. The thickness of the insulation layer is 100mm.
4. Temperature and humidity circulation system: It adopts a special air-conditioning type low-noise long-axis fan motor and a stainless steel multi-wing impeller that is resistant to high and low temperatures.
to achieve intensive convection vertical diffusion circulation
5. Double-layer high-temperature-resistant high-tensile sealing strips are used between the door and the box to ensure the sealing of the test area.
6. The use of non-reaction door handles makes operation easier
7. The bottom of the walk-in constant temperature and humidity test chamber adopts high-quality fixable PU movable wheels.
8. The observation window is made of multi-layer hollow tempered glass, and the inside of the glued conductive film is heated and defrosted (clearly observe the test process)
9. The test hole (left side of the machine) can be connected to an external test power cord or signal
