Overview
NBC-50L-20 (paint plate) programmable constant temperature and humidity testing machine is a factory direct sales of high and low temperature heat and humidity alternating test chamber, mainly used to detect the performance of materials in various environments, test the heat resistance of various materials, cold resistance, dry resistance, moisture resistance performance. The equipment is suitable for mass testing 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.
2. The controller uses a large-scale color liquid crystal man-machine touch dialog LCD man-machine interface, which displays the operating status of the system in both Chinese and English, and supports RS232 computer interface remote control.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor or French Taikang Compressor. The components come from Japan, France, the United States, Italy and other origins, and the refrigerant adopts American environmentally friendly refrigerant.
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, the trend and return air sensor detection and control, to ensure that the temperature is uniform without 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, and 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, 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 of 220V/50HZ, and 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.
4. Start the equipment and monitor the operating status of the system to ensure uniform temperature.
5. After the test is completed, it will automatically shut down and check for fault prompts.
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.
Maintain Compressor and Sensor regularly to ensure long-term stability.
