Overview
Programmable constant temperature and humidity testing machine (model NBC-408L-40) is mainly used to detect the performance of materials in various environments, test heat resistance, cold resistance, dry resistance and moisture resistance characteristics. It is suitable for mass inspection of products in the fields of electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemistry, building materials, aerospace and other fields. Adopt equilibrate Conditioning control system, transmit data to the controller through the induction system, intelligent output power to ensure stable temperature and humidity, with energy saving function.
Features
1, beautiful appearance, reasonable structure, precision technology, 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 (optional French Taikang), and the components are imported from Japan, France, the United States, Italy, etc., using American environmentally friendly refrigerant.
4. Reserve a 50mm diameter test hole on the left side of the test chamber.
5, With 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 area.
6. Specially designed air circulation system and sensing system ensure uniform temperature without dead ends.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wide field of vision.
8. Comprehensive protection system includes power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm sound prompt, automatic display of fault points and shutdown.
Principle
Adopting equilibrate Conditioning control system, the induction system transmits the actual data in the box to the controller. The controller controls SSR and multi-stage intelligent output, and the equilibrate temperature and humidity system outputs power to ensure stable temperature and humidity. The system has energy-saving function, reduces power consumption, and ensures long-term accurate 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 380V/50HZ, and the allowable value of variation is +/- 10%.
2. Set the temperature and humidity parameters through the controller, and operate with a large color LCD touch interface.
3. Place the sample on the shelf, with 1 layer as standard, up to 4 layers can be placed, and the layer spacing is adjustable.
4. Start the instrument, and the system automatically controls the temperature and humidity to monitor the operating status.
5. After the test is completed, turn off the instrument and remove the sample.
Notice
• The use environment temperature should be maintained at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items should not be placed within 60cm of the instrument to ensure ventilated and normal operation.
• Use the built-in water tank and drawer water box when adding water, and pay attention to the water quality filtrating to avoid blockage.
• Use the bottom 4 high-bearing heavy-duty universal wheels when moving the instrument, pay attention to shock absorption and smooth movement.
• Regularly check the protection system, automatically shut down in case of failure, and deal with the failure point in time.
