Overview
NBC-800L-20 programmable constant temperature and humidity testing machine is a high and low temperature heat and humidity alternating test chamber sold directly by the factory. It is mainly used to detect the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance and moisture resistance 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, with Chinese and English display, and supports RS232 computer interface remote control.
3. The refrigeration circulation system adopts the original imported Japanese Sanyo fully enclosed Compressor, and the components come from Japan, France, the United States, Italy, etc. 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. Equipped with Fully Automatic, High Precision System Loop, P.L.C Locking 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 whole empty 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, etc., which automatically displays faults 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, 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 380V/50HZ requirements.
2. Open the test chamber door and place the test sample on the shelf.
3. Set the temperature and humidity parameters and program Linear dispersion through the controller.
4. Start the equipment and monitor the operating status.
5. After the test is completed, turn off the device and remove the sample.
Notice
• The use environment temperature should be in the range of 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items cannot be placed within 60CM of the equipment.
• Power supply voltage variation within +/- 10%.
• The humidification system has water quality filtrating, regular inspection to avoid blockage.
• The instrument has a variety of protection functions, and it automatically stops when there is an abnormality. It is necessary to deal with the fault in time.
