LED Constant Temperature and Humidity Test Chamber used to test LED material  for their tolerances of heat, cold, dry, humidity.



 1. Graceful appearance, circularly shaped body for , surface treated with mist strips and plane handle with no reaction. Our temperature humdity climatic chamber is easy to operate, safe and reliable. 

2. Rectangular double-glassed watching window for the observation of the test production during the testing process. 

The window is equipped with sweat-proof electrical heating device that can prevent water steam from condensing 

into droplets, and with high brightness PL fluorescent bulbs to provide light inside the box. 

3. Double-layer-insulated airtight doors, able to insulate the internal temperature effectively. 

4. Water supply system that is externally connectable, convenient for refilling water into the humidifying pot and 

automatically recyclable. 

5. The French Tecumseh brand is used for the circulation system of the compressor, capable of removing the

 lubricant between the condensation pipes and capillaries. The environment protecting coolant is used for the 

whole series (R23, R404A

6. Imported LCD display screen, capable of displaying the measured value as well as the set value and time. 

7. The controller of environmental chamber has the functions of multiples segment program editing, and of quick or slope control of temperature and humidity. 

8. Inserted mobile pulley, convenient for movement an relocation, with strong positioning screws.
