Overview
AISRY ASR-50L-70 programmable constant temperature and humidity testing machine is a testing equipment used to simulate various temperature and humidity environments. 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 adopts equilibrate Conditioning Control System (BTHC), which ensures that the temperature and humidity in the box are fully stable through intelligent control, and has energy-saving functions. It 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.
The controller uses a large color liquid crystal man-machine touch dialog LCD interface, with Chinese and English display, simple operation, and can realize remote control of RS232 computer interface.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (purchased from France Taikang Compressor), the core components are imported, and the American environmentally friendly refrigerant is used.
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, temperature control with High Accuracy and High Stability.
6. Specially designed air circulation circulation 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, control loop overload short circuit, Compressor, grounding, overtemperature protection, etc., automatically display and stop when the fault.
Principle
The equipment adopts equilibrate Conditioning Control System (BTHC). The induction system transmits the actual temperature and humidity data in the test chamber to the controller. The controller controls the SSR (solid state relay) to equilibrate the output power of the temperature and humidity system in a multi-stage intelligent output mode, thus ensuring that the temperature and humidity in the test chamber are fully stable. The system also has an energy-saving function, which can reduce the power of the instrument to a greater extent 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
GB5170,2,3,5,6-95 "Environmental test basic parameter method of verification high temperature, constant heat and humidity, alternating humidity cabinet test equipment", GB 2423.2-89 (IEC68-2-2), GB/T 2423.3-93 (IEC68-2-3), GB/T423.4-93 (IEC68-2-30)
Steps
1. Preparation: Ensure that there are no Miscellaneous items within 60cm of the equipment and no serious tilt of the ground.
2. Connection: Connect the 220V/50HZ power supply (voltage allowed to vary by +/- 10%).
3. Settings: Through the 7-inch color touch screen controller, select the Chinese/English interface for program editing and parameter setting.
4. Place the sample: Place the sample to be tested on the shelf with adjustable spacing in the box.
5. Start: Select or start the set temperature and humidity program, and the device starts running.
6. Monitoring: Real-time observation of the program Linear dispersion execution status, actual value of temperature and humidity and remaining time through the controller screen.
7. End: After the program is completed, the device can be stopped according to the setting and the sample can be taken out.
Notice
• The recommended environment temperature is 0~ 30 ° C (working environment temperature 5~ 25 ° C).
• Miscellaneous items should not be placed within 60CM of the instrument.
• The installation ground should not be severely tilted.
• Pay attention to the voltage requirements on the equipment nameplate (220V/50HZ), and the allowable voltage variation is +/- 10%.
• The equipment has a comprehensive protection function. When a fault alarm occurs, please check according to the screen prompt information, and do not force the operation.
• When using the humidification system, please pay attention to the use of its water circulation and water quality filtrate functions to save water and reduce the frequency of cleaning.
• When conducting low temperature tests, the equipment uses a circular split humidifier to avoid freezing in the sink.
• There is a test hole reserved on the left side of the equipment, please pay attention to the protection of the wiring harness when using it.
