Overview
Programmable constant temperature and humidity testing machine NBC-100L-40 is a factory direct high and low temperature heat and humidity alternating test chamber, mainly used to test the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance, moisture resistance performance of various materials. It 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.
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 are imported from Japan, France, the United States, Italy, etc., and the American environmentally friendly refrigerants R23A and R404A are used.
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 and ensure that the voltage is within the allowable fluctuation value of +/- 10%.
2. Set the temperature and humidity program through the controller Linear dispersion.
3. Place the items to be tested on the shelf, up to 4 layers.
4. Start the instrument and monitor the operating status.
5. After the test is completed, turn off the instrument and disconnect the power supply.
Notice
• The use environment temperature should be maintained at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items cannot be placed within 60CM of the instrument.
• Regularly check the water quality of the humidification system to filtrate and avoid blockage.
• Use the bottom universal wheel when moving the instrument, pay attention to shock absorption and load-bearing.
• When a failure occurs, the instrument automatically stops and displays the fault point, which needs to be dealt with in time.
