The three-chamber thermal shock testing machine area is divided into three parts: high temperature area, low temperature area, and test area. The cabinets of each area adopt a unique heat insulation structure. The impact method uses the wind circuit switching method to introduce the temperature into the test area for thermal and thermal shock tests. During high temperature shock or low temperature shock, the maximum time can reach 9999 minutes, and the maximum cycle can reach 9999 times. The system can be used for automatic cycle impact or manual selective impact, and can set two or three zones of impact and the start of cold punch and hot punch. The cooling adopts binary refrigeration system, the cooling effect is fast, and the cooling method is air-cooled or water-cooled. It can be connected to a computer, and the Recorder is only an optional part. It adopts color Chinese and English LCD touch-control graphical operation interface, which is easy to operate.

The three-slot thermal shock testing machine is used to test whether the product is adversely affected due to rapid changes in high-low temperatures without moving the item to be tested. It is generally used for electronic components, auto parts and high-tech products, etc.; it requires harsh Environmental condition test and inspection of high reliability endurance requirements.
1. The product has beautiful appearance, reasonable structure, professional technology and exquisite material selection. The air-cooled thermal shock Test Chamber has simple and convenient operation performance and reliable equipment performance.
2. The equipment is divided into three parts: high temperature box, low temperature box, and test box. It adopts a unique heat insulation structure and heat storage and cold storage effect. During the test, the object to be tested is completely static, and the cold and hot temperatures are introduced into the test by switching between hot and cold air channels. The area realizes the purpose of thermal shock test.
3. Adopt professional measurement device, the controller adopts large-scale color LCD man-machine touch conversational LCD man-machine interface controller, easy to operate, easy to learn, stable and reliable, complete system operation status, execution and operation status are displayed in Chinese and English Set the program curve.
4. There are 96 test specifications independently set, the impact time is 999 hours and 59 minutes, and the cycle period can be set from 1 to 999 times, which can realize the automatic operation of the refrigerator, better realize automation, reduce the workload of the operator, and can be used at any time The time automatically starts and stops working;
5. There is a test hole with a diameter of 50mm on the left side of the box, which can be used for external power load wiring test components.
6. It can independently set the function of three different conditions of high temperature, low temperature and hot and cold shock, and when performing the cold and hot shock conditions, you can choose the two-slot or three-slot type and the function of cold punching and hot punching. high-low temperature testing machine
7. It can be used independently as a high-temperature box or a low-temperature box, one machine with three functions.
8. Equipped with full-automatic, high-precision system loops, any part action, complete PLC locking processing, all adopt PID automatic calculation control, high temperature control accuracy.
9. The professional and scientific air circulation design makes the indoor temperature uniform and avoids any dead angle; the complete safety protection device avoids any possible safety hazards and ensures the long-term reliability of the equipment.
10. The number of cycles and the number of defrosts can be set for automatic (manual) defrosting.
11. The sensor detection and control of the air outlet and the return air outlet, the switching time of the damper mechanism is completed within 10 seconds, and the recovery time of the cold and heat shock temperature is completed within 5 minutes.
12. Status display and curve display during operation. When an abnormal situation occurs, the fault point and cause will be automatically displayed on the screen immediately and the method of troubleshooting will be provided. When the input power is found to be unstable, it will have an emergency stop device.
13. The refrigeration system adopts the design of cascade effective low-temperature loop system. The refrigeration unit adopts imported compressors from Europe and America, and uses green environmental protection (HFC) refrigerants R507 and R23 with zero ozone coefficient.
14. Super safety protection functions: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over temperature protection, alarm sound prompt, etc.
