Overview
Programmable constant temperature and humidity testing machine is mainly used to test the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. Suitable for mass testing of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products.
Features
1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation, stable and reliable performance.
The controller uses a large color liquid crystal man-machine touch dialog LCD interface, which is easy to operate, easy to learn, stable and reliable. It displays the operating status of the system in both Chinese and English, and supports remote control of RS232 computer interface.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor, the components come from Japan, France, the United States, Italy and other origins, and the refrigerant is the American environmentally friendly refrigerant (R23A, R404A).
4. A 50mm diameter test hole is reserved on the left side of the test chamber.
5. Equipped with Fully Automatic, High Precision System Loop, P.L.C Locking Processing, P.I.D Automatic Calculation Control, High Accuracy and High Stability of Temperature in the Whole Zone.
6, special design air circulation circulation system and sensing system, the trend and return air sensor detection and control, to ensure Temperature Uniformity, avoid dead angle.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wide field of vision.
8. The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm sound prompt, and automatically display the fault point and stop when abnormal.
Principle
The equilibrate Conditioning Control System (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR, multi-stage intelligent output, and the output power of the equilibrate temperature and humidity system to ensure that the temperature and humidity in the test chamber are fully stable. It has energy-saving functions, reduces the use of power, and ensures long-term accurate and stable operation of the instrument.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
1. Connect the power supply to ensure that the voltage meets the requirements.
2. Set the temperature and humidity parameters and program Linear dispersion through the controller.
3. Start the instrument, and the system will automatically run and monitor.
4. Observe the testing process, and automatically shut down if there is any abnormality and display any malfunctions.
5. After the test is completed, turn off the instrument and disconnect the power supply.
Notice
• The use environment temperature should be maintained at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items should not be placed within 60cm of the instrument.
• Power supply voltage within the allowable range of +/- 10%.
• Check whether all protection systems are normal before operation.
• When there is an abnormal situation, the instrument will automatically shut down, and the fault needs to be dealt with in time.
