Walk-in constant temperature and humidity room is for high-performance electronic products (such as: computer machines, monitors, terminals, automotive electronics, power supply, motherboards, monitors, switching chargers, etc.) simulation of a high temperature, harsh environment testing equipment, is to improve the stability of products, reliability of important experimental equipment, is an important production process to improve product quality and competitiveness of the production enterprises.
Function:
This product is manufactured according to user requirements with reference to GB2423[1].02 high temperature test method, GB2423[1].01 low temperature test method, GB2423[1].03 constant humidity and heat test method, GB2423[1].04 alternating humidity and heat test method corresponding technical conditions. Mainly for aerospace, aviation, petroleum, chemical, automotive (motorcycle), shipping, electronics, communications and other scientific research and production units to provide temperature and humidity changes in the environment for users of the whole machine (or parts), electrical appliances, instruments, materials, etc. for temperature and humidity tests, in order to assess the adaptability of the test product or the behavior of the test product to make an evaluation. It is an important test means essential to the whole process of new product development, prototype test and product qualification test.
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
