Overview
NBC-50L-40 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 color liquid crystal man-machine touch dialog LCD interface, which is easy to operate, easy to learn, stable and reliable. It supports Chinese and English display and 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 come 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 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 to ensure Temperature Uniformity and avoid dead ends.
7. Adopt enlarged observation window, 4 layers of tempered Glass, wide field of vision.
8. 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, automatically display the fault point and stop.
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
1. Ensure that there are no Miscellaneous items within 60CM of the instrument, and the ground is not seriously tilted.
2. Connect the power supply and allow the voltage to vary by +/- 10%.
3. Set the temperature and humidity parameters through the touch screen controller, and use the P.I.D automatic calculation control.
4. Start the instrument, monitor the operating status, and automatically shut down if there is any abnormality and display the fault.
5. After the test is completed, turn off the instrument and disconnect the power supply.
Notice
- Miscellaneous items cannot be placed within 60CM of the instrument.
The installation ground must not be severely tilted.
- The recommended environment temperature is 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
- Regularly check the water quality of the humidification system to infiltrate and avoid blockage.
- Pay attention to the instrument protection system, automatically shut down in case of failure, and deal with it in time.
