The box is processed by numerical control machine tool, beautiful and easy to operate.
Features
1. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate, and the shell is sprayed with A3 steel plate
2. Large observation window with lighting to keep the box bright, using heating element embedded tempered Glass clear observation
3. The left side of the box is equipped with a 50mm diameter test hole, which can be used for external test power cord or signal cable
4. Temperature control adopts "7.0" inch large-screen Touchscreen temperature and humidity control instrument, and the operation setting is simple
5. The controller has a locking function to avoid human touch to change the temperature value
6. With P.I.D automatic calculation function, the temperature control is more accurate and stable
7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit
8. The multi-wing blower is used for strong air circulation, and the temperature distribution in the test area is uniform
9. Air circuit circulation air outlet and return air design, wind pressure and wind speed meet the test standards
10. Heating, cooling, and complete system independence can improve efficiency and reduce testing costs
Principle
The test chamber is designed by the French Taikang fully enclosed Compressor unit and low temperature circuit system through the refrigeration system, combined with the strong air supply circulation of the multi-wing blower, to achieve uniform temperature distribution. The temperature control adopts the P.I.D automatic calculation function, and the temperature is accurately adjusted by the large-screen Touchscreen temperature and humidity control instrument to ensure the stable and reliable test environment.
