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 key components come from Japan, France, the United States, Italy and other places, and the United States uses 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, using P.I.D automatic calculation control to ensure High Accuracy and High Stability.
6. Specially designed air circulation circulation system and sensing system to avoid temperature dead angle and ensure Temperature Uniformity in the box.
7. Adopt enlarged observation window, equipped with 4 layers of whole space 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, overtemperature and other protection, and automatically displays and stops when the fault occurs.
Principle
The testing machine adopts the equilibrate Conditioning control system. The induction system transmits the actual temperature and humidity data in the box to the controller. The controller controls the SSR (solid state relay) for multi-stage intelligent output, and equilibrates the output power of the temperature and humidity system to ensure that the temperature and humidity in the box are fully stable. At the same time, the system has the function of energy saving, which can reduce the power used and ensure 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
Standards

Steps
1. Preparation: Make sure that the instrument is placed in an area with an environment temperature of 0~ 30 ° C and no Miscellaneous items within 60cm of the surrounding area, and connect the 220V/50HZ power supply (voltage variation is allowed +/- 10%).
2. Boot and Settings: Turn on the power, perform human-machine interaction through a 7-inch color touch screen controller, select the Chinese and English interface, and use the touch screen to directly press the button to set the temperature and humidity program Linear dispersion.
3. Program editing: Enter the separate program editing screen, edit, clear, and insert program segments, and enter at least 5 segments of temperature, humidity, and time per page, with a maximum support of 120 sets of programs and 1200 partial memory capacity.
4. Place the sample: Open the double-decked door on the left, place the sample on the SUS304 stainless steel rack (standard 1 layer, up to 4 layers can be placed, and the layer distance is adjustable), and then close the door to ensure sealing.
5. Start test: After the setting is completed, start the program, the controller will automatically perform temperature and humidity control, and the screen will display the program Linear dispersion, execution status and remaining time in real time.
6. Monitoring and completion: During the test, the instrument runs automatically and has a protective function; after the test is completed, remove the sample and turn off the power.
Notice
• Use environment requirements: The working environment temperature is recommended to be 5~ 25 ° C, to ensure that Miscellaneous items cannot be placed within 60cm around the instrument to ensure heat dissipation and stable operation.
• Power supply safety: When connecting the power supply, it must meet the requirements of 220V/50HZ, and the allowable value of voltage variation is +/- 10% to avoid overload use.
• Operational safety: The instrument has a comprehensive protection system (such as overload, leakage, and over-temperature protection), but care should be taken to avoid touching internal high-temperature or charged parts during operation.
• Maintenance: Regularly check the water quality filtrating device of the humidification system to avoid blockage; use a drawer type water filling box to facilitate water addition, and pay attention to the water circulation system to save water.
• Fault handling: If the instrument fails, the screen will automatically display the fault point and cause and shut down. Please do not disassemble it yourself, and contact a professional for maintenance.
• Moving and placing: The bottom of the instrument is equipped with 4 high-bearing heavy-duty universal wheels. When moving, it needs to be pushed and pulled smoothly. After placing, make sure that the casters are locked to prevent sliding.
• Use of test hole: The diameter of the test hole on the left side is 50mm. Pay attention to the protection of the wiring harness when using it to avoid damage to the sealing material.
