Overview
Programmable constant temperature and humidity testing machine NBC-100L-20 is a device used to test the performance of materials in various environments, mainly used to test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. The equipment is suitable for mass detection of electronics, electrical appliances, communications, meters, 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, supports Chinese and English display, and can realize 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 come from Japan, France, the United States, Italy and other origins, 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, using P.I.D automatic calculation control, the whole area temperature High Accuracy, High Stability.
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 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., which automatically displays the fault point and stops.
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 the 220V/50HZ requirements.
2. Open the test chamber door and place the items to be tested on the shelf.
3. Set the temperature and humidity parameters and program Linear dispersion through the controller.
4. Start the instrument and monitor the operating status.
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.
Allows the use of environment temperature is 0~ 30 ℃, the performance of the environment temperature is 5~ 25 ℃.
• Power supply voltage variation allowable value is +/- 10%.
• Check the water quality of the humidification system before use to avoid blockage.
• Use the bottom universal wheel when moving the instrument to ensure smoothness.
