Overview
NBC-50L-40 (paint plate) 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 detection 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-scale color liquid crystal man-machine touch dialog LCD interface, with Chinese and English display, and supports RS232 computer interface remote control.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (optional French Taikang), the components are imported from Japan, France, the United States, Italy, etc., and the refrigerant is the American environmentally friendly refrigerant (R23A, R404A).
4. Reserve a 50mm diameter test hole on the left side of the test chamber.
5, with automatic, high-precision system loop, P.L.C lock processing, all using P.I.D automatic calculation control, the whole area temperature High Accuracy, High Stability.
6, special design of air circulation circulation system and sensing system, the trend and return air sensor detection and control, to ensure uniform temperature, 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 prompts, etc., and automatically displays the fault point and stops 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, 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 the requirements (220V/50HZ, the allowable value of variation is +/- 10%).
2. Set the temperature and humidity parameters through the touch screen controller, and use P.I.D automatic calculation control.
3. Place the test sample on the shelf and adjust the layer spacing (maximum 4 layers).
4. Start the instrument to monitor temperature and humidity changes to ensure uniformity and stability.
5. After the test is completed, turn off the instrument and remove the sample.
Notice
• Miscellaneous items should not be placed within 60CM of the instrument.
• The installation ground should not be severely tilted.
• The working environment temperature should be kept at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Check whether the protection system is normal before use to avoid abnormal operation.
• Regularly maintain the Compressor and refrigeration system to ensure long-term stable operation.
