Overview
GDJW-500D high and low temperature alternating test chamber is a ZKHS brand product, suitable for the performance detection of aviation, aerospace products, information electronics, Instruments, materials, electricians, electronic products and various electronic components in high and low temperature environments. The equipment adopts advanced control system and refrigeration system to ensure stable and reliable test environment.
Features
1. The box is processed by numerical control machine tool, which is beautiful and easy to operate
2.The liner adopts imported stainless steel (SUS304) mirror plate, and the shell adopts A3 steel plate spray
3. Large observation window with lighting, embedded tempered Glass, clear observation
4. 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
5. Adopt 7.0-inch large-screen Touchscreen temperature and humidity control instrument, simple operation setting
6. The controller has a locking function and P.I.D automatic calculation function, and the temperature control is accurate and stable
7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit
8. Multi-wing blower with strong air circulation, uniform temperature distribution
9. The heating and cooling systems are completely independent, effectively reducing test costs and failure rates
Principle
The equipment realizes temperature control through heating system and refrigeration system, and adopts multi-wing blower for strong air supply circulation to ensure uniform temperature distribution in the test area. The control system corrects the temperature change in real time through P.I.D. automatic calculation, and the air circuit circulation design makes the temperature return to stability at the moment of opening the door fast to ensure the stability of the test environment.
