Overview
AISRY ASR-225L-70 programmable constant temperature and humidity tester is a device used to test the performance of materials in various environments (such as high temperature, low temperature, heat and humidity). It is suitable for testing the performance of heat resistance, cold resistance, dry resistance and moisture resistance of products. It adopts equilibrate Conditioning control system to ensure stable temperature and humidity in the box through intelligent control, and has energy-saving functions. It is suitable for mass inspection of products in many fields such as electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace, etc.
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 key components are imported, and the refrigerant is an environmentally friendly refrigerant from the United States.
4. Reserve a 50mm diameter test hole on the left side of the box.
5, with automatic, high precision system loop, using P.I.D automatic calculation control, high temperature control accuracy, Stability.
6. Specially designed air circulation system and sensing system ensure uniform temperature in the box and avoid dead ends.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wide field of vision.
8, with a comprehensive protection system, including power overload, leakage, short circuit, Compressor, overtemperature and other protection, fault automatically display and stop.
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 solid-state relay and uses a multi-stage intelligent output mode to equilibrate 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 an energy-saving function, 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
Steps
Connect the power supply to ensure that the voltage meets the requirements (220V/50HZ, allowing a change of +/- 10%).
2. Perform parameter setting through the controller (7-inch color touch screen), select Chinese and English interfaces, and edit the temperature and humidity program Linear dispersion.
3. Place the sample to be tested on the shelf (standard configuration 1 layer, adjustable layer distance).
4, close the door (left single door, double-decked design, with sealing strip).
5. Start the test program, and the controller automatically executes the set temperature and humidity change process.
6. During the test, it can be viewed in real time through the observation window, or remotely monitored through the RS232 interface.
7. After the test is completed, the instrument automatically stops and the sample is taken out.
Notice
• The recommended environment temperature is between 0 and 30 ° C, preferably 5 to 25 ° C.
• Miscellaneous items should not be placed within 60cm of the instrument to ensure heat dissipation and air circulation.
• When adding water, use the built-in drawer type water box, pay attention to the water quality filtrate, and avoid the blockage of the humidification system.
• When moving the instrument, you can use the bottom high-bearing heavy universal wheel to pay attention to stability.
• Test hole (50mm on the left) for leads, pay attention to harness protection.
• The instrument has a variety of protection functions. In case of fault alarm, please check and eliminate according to the screen prompts.
• Regularly maintain the refrigeration system (e.g. Compressor, refrigerant) and heating/humidification system to ensure long-term stable operation.
• Avoid opening the door frequently when the instrument is running, so as not to affect the uniformity of temperature and humidity and the test accuracy.
