Overview
AISRY ASR-150L-60 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 heat resistance, cold resistance, dry resistance and moisture resistance performance of products. The equipment adopts equilibrate Conditioning Control System (BTHC), which transmits the data in the box to the controller through the induction system. The controller intelligently adjusts the output power to ensure stable temperature and humidity, and has energy-saving functions.
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 (optional French Taikang), the core components are imported, and the refrigerant adopts American environmentally friendly refrigerant (R23A, R404A).
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, control loop overload/short circuit, Compressor, grounding, over-temperature protection, etc., automatically display and stop when the fault.
Principle
The equipment adopts equilibrate Conditioning Control System (BTHC). The system collects the actual temperature and humidity data in the test chamber through the sensor and transmits it to the controller. According to the setting program, the controller precisely adjusts the power output of the heating, cooling, humidification, dehumidification and other systems by controlling the multi-stage intelligent output such as solid state relay (SSR), so as to equilibrate and stabilize the temperature and humidity environment in the box. The refrigeration system adopts a Compressor forced refrigeration cycle with an energy-saving regulating valve; the humidification system adopts a split humidifier; the heating system adopts a multi-stage heating tube to achieve accurate temperature and humidity control together.
Applications

Standards
The data did not mention specific compliance criteria
Steps
Connect the power supply to ensure that the voltage meets the requirements (220V +/- 10%).
2. Set the required temperature and humidity program Linear dispersion through the controller (7-inch color touch screen), which can be edited, inserted, cleared and other operations.
3. Put the sample to be tested into the shelf in the box and close the box door to ensure sealing.
4. Start the running program, and the equipment starts to test the temperature and humidity changes according to the set Linear dispersion.
5. During operation, the program execution status, remaining time, and the actual temperature and humidity value in the box can be monitored in real time through the observation window and controller screen.
6. After the test is completed, the device can be set to stop or stand by to remove the sample.
Notice
• The recommended working environment temperature of the equipment is between 0 and 30 ° C (or 5 and 25 ° C).
• Miscellaneous items should not be placed within 60CM of the equipment to ensure heat dissipation and air circulation.
• Pay attention to the equipment Power supply voltage requirements and the allowable range of changes.
• Use the built-in drawer water box when adding water, and pay attention to the maintenance of the water quality filtrating system.
• Use the bottom universal wheel when moving the device, pay attention to stability.
• Check whether each protection device is normal before operation, and check immediately in case of fault alarm.
• When conducting low temperature tests, be aware that the humidification system may freeze. This equipment uses a split humidifier to avoid this problem.
• The shelf has a load limit (single layer 20KG), please do not overload.
