Overview
Programmable constant temperature and humidity testing machine is a kind of equipment for testing the performance of materials in various environments, testing the performance of materials heat resistance, cold resistance, dry resistance and moisture resistance. 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.
2. The controller adopts a large-scale color liquid crystal man-machine touch dialog LCD interface, which 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 (optional French Taikang), the components are from Japan, France, the United States, Italy, etc., and the refrigerant is an environmentally friendly refrigerant in the United States.
4. Reserve a 50mm diameter test hole on the left side of the test chamber.
5. With Fully Automatic, High Precision System Loop, P.L.C Lock Processing, P.I.D Automatic Calculation Control, High Accuracy and High Stability of Temperature in the Whole Zone.
6. Specially designed air circulation circulation system and sensing system, trend and return air sensor detection and control to ensure uniform temperature without dead ends.
7. Adopt enlarged observation window, 4 layers of tempered Glass, wide field of vision.
8. The instrument has a comprehensive protection system, including power overload, leakage, control loop overload, short circuit, Compressor, grounding, over-temperature protection and alarm sound prompts, automatic display fault and shutdown.
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 and multi-stage intelligent output, and the equilibrate temperature and humidity system outputs the power to ensure that the temperature and humidity in the test chamber are fully stable, and It has the function of energy saving, reducing the power of the instrument, and ensuring long-term accurate and stable operation.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
Connect the power supply to ensure that the voltage meets 220V/50HZ, and the allowable value of variation is +/- 10%.
2. Turn on the instrument and use the controller to set the temperature and humidity parameters, such as Temperature range -20~ 150 ℃, humidity control range 20~ 98% R.H.
3. Start the test, monitor the system automatically, and observe the test process through the observation window.
4. 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 around the instrument to avoid affecting the performance.
• Pay attention to protection functions such as power overload and leakage to ensure safe operation.
• Regularly check the Compressor and refrigeration system to ensure normal operation.
