Overview
NBC-408L-60 (paint plate) programmable constant temperature and humidity tester is mainly used to detect the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. The equipment adopts equilibrate Conditioning Control System (BTHC), which transmits the actual data in the test chamber to the controller through the induction system. The controller realizes multi-stage intelligent output by controlling SSR, and the output power of the equilibrate temperature and humidity system ensures that the temperature and humidity in the test chamber are fully stable, and has the function of energy saving, reducing the power of the instrument and ensuring long-term accurate and stable operation.
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 man-machine interface, which is easy to operate, easy to learn, stable and reliable. The complete system operation status, execution and setting procedures are displayed in both Chinese and English. Linear dispersion supports RS232 computer interface remote control.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (optional French Taikang Compressor), the components come from Japan, France, the United States, Italy and other origins, and the refrigerant adopts American environmentally friendly refrigerant (R23A, R404A).
4. A 50mm diameter test hole is reserved on the left side of the test chamber.
5, with fully automatic, high-precision system loop, any part action with P.L.C locking processing, all using P.I.D automatic calculation control, the whole area temperature with 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 that the test chamber Temperature Uniformity, avoid dead ends.
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 and sound prompts, etc., and automatically displays the fault point and cause 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 realizes multi-stage intelligent output by controlling the SSR, and the output power of the equilibrate temperature and humidity system ensures that the temperature and humidity in the test chamber are fully stable. It has energy-saving functions, reduces the power of the instrument, and ensures long-term accurate and stable operation.
Applications
Electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products testing mass
Steps
Connect the power supply and ensure that the voltage meets the requirements (380V/50HZ, the allowable value of variation is +/- 10%).
2. Set the required temperature and humidity program through the controller Linear dispersion.
3. Start the equipment for testing and monitor system operation.
4. After the test is completed, turn off the device according to the program.
Notice
The working environment temperature should be kept at 0~ 30 ℃.
• The performance guarantee ambient temperature range is 5~ 25 ℃.
• Use environment requirements: Miscellaneous items cannot be placed within 60CM of the equipment.
• Power supply voltage and power requirements to avoid overload.
• Regularly check the protection system function to ensure safe operation.
