Overview
NBC-225L-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, 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. Adopt large-scale color liquid crystal man-machine touch dialog LCD controller, display in both Chinese and English, and support RS232 computer interface remote control
3. The original imported Japanese "Sanyo" brand fully enclosed Compressor is used, and the refrigerant is American environmentally friendly refrigerant
4. Reserved 50mm diameter test hole on the left side of the test chamber
5, with automatic high-precision system loop, using P.I.D automatic calculation control, high temperature accuracy, Stability
6. Specially designed air circulation system to ensure uniform temperature in the box without dead ends
7. Adopt enlarged observation window, 4 layers of tempered Glass, wide field of view
8. With a comprehensive protection system, including power overload protection, leakage protection, over-temperature protection, etc., it automatically displays faults and stops
Principle
Using equilibrate Conditioning control system (BTHC), the induction system transmits the actual data in the box 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 box are fully stable. The system has the function of energy saving, reducing the power used, and ensuring the long-term accurate and stable operation of the instrument.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
1. Turn on the power supply and check whether the voltage meets the requirements
2. Set test parameters and procedures through the human-machine touch interface Linear dispersion
3. Place the sample to be tested on the shelf
4. Start the test program and the instrument will run automatically
5. Sample status can be monitored through the observation window during the test
6. After the test is completed, the instrument automatically stops and displays the results
Notice
• The operating environment temperature should be kept within the range of 0~ 30 ° C
• performance guarantee environment temperature of 5~ 25 ℃
• Miscellaneous items should not be placed within 60cm of the instrument
• Power supply voltage variation allowable value is +/- 10%
• Use the built-in water tank and drawer water filling box when adding water
• Regularly check the water filtrating system to avoid clogging
• Use the bottom universal wheel when moving the instrument, pay attention to the load-bearing limit
• The single-layer load of the shelf does not exceed 20KG
