Product Introduction
The high and low temperature humidity and heat alternating test chamber is mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dry resistance and moisture resistance of various materials. It is suitable for testing the quality of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products.
Control mode: The balanced temperature and humidity control system (BTHC) is adopted, the induction system transmits the actual data in the test chamber to the controller, and the controller balances the output power of the temperature and humidity system by controlling SSR, multi-stage intelligent output, to ensure that the temperature and humidity in the test chamber are fully stable, and has energy-saving functions, which greatly reduces the power of the instrument and ensures the long-term accurate and stable operation of the instrument.
Product features:
1. The product has beautiful appearance, reasonable structure, precise technology, simple and convenient operation and stable and reliable performance.
2. The controller adopts a large color LCD human-machine touch dialog LCD human-machine interface controller, which is simple to operate, easy to learn, stable and reliable, and displays the complete system operation status, execution and setting program curves in Chinese and English, which can realize RS232 computer interface docking.Control the instrument remotely directly from your computer.
3. The refrigeration circulation system adopts compressor: the original imported Japanese "Sanyo" brand fully enclosed compressor (purchased by French Taikang compressor), each component is imported parts, from Japan, France, the United States, Italy and other production areas, and the refrigerant is made of American environmentally friendly refrigerant (R23A, R404A).
4. There is a test hole with a diameter of 50mm on the left side of the test box.
5. It has a fully automatic, high-precision system loop, any machine operation, with P.L.C locking processing, all of which adopt P.I.D automaticCalculation control, the temperature of the whole area has high precision and high stability.
6. Specially designed air circulation and air circulation system and sensing system, the air outlet is detected and controlled by the return air outlet sensor to ensure the temperature uniformity in the test chamber and avoid any dead ends.
7. The use of enlarged observation window and 4 layers of hollow tempered glass for a wider field of view.
8. The instrument has a multi-position protection system, power overload protection, leakage protection, control loop overload, short circuit protection, compressor protection, grounding protection, over-temperature protection, alarm sound prompt, etc., when any abnormal situation occurs, the screen will automatically display the fault point and cause and automatically stop the machine.
