I. Applications of the Intelligent Constant Temperature and Humidity Test Chamber
This equipment is primarily designed for testing the adaptability of electrical equipment, electronic products, their components, and other materials under high and low temperatures, as well as in humid and cyclic conditions during storage, transportation, and use. The test equipment is mainly used to simulate environmental conditions according to national standards or customer-defined requirements, and to assess the physical and other related properties of products under alternating high, low temperature, and humidity cycles. After testing, the performance of the products is evaluated through inspections to determine if they still meet the specified requirements, for product design, improvement, certification, and factory inspection purposes.

IV. Structural Characteristics of the Equipment
1. The equipment is mainly composed of the housing, refrigeration system, air circulation system, and control system.
2. The cabinet shell is made of cold-rolled steel plates with double-sided electrostatic spraying, the inner lining is made of SUS304 stainless steel plate. The door is equipped with a large observation window in the middle, complete with an observation light, allowing users to clearly see the test condition of the sample.
3. The overall appearance is elegant and tasteful. The insulation layer is ultra-fine glass wool, featuring high strength and excellent thermal insulation properties.
4. Equipped with a human-machine dialogue operation mode, an imported full-color touch screen temperature and humidity controller. It achieves automatic operation of set values, cycles, and programs. The curve of operating data can be automatically saved or connected to a computer for remote control. Features on/off control and AI artificial intelligence adjustment functions, with 0.2-grade accuracy and various alarm modes. Capable of heating, cooling, humidity control, and maintaining constant temperature and humidity, with a unique BTHC balanced temperature adjustment method.
5. The refrigeration system features a fully enclosed imported compressor set from Europe's Tecumseh, with a mechanical single-stage refrigeration or cascade low-temperature circuit system, and an automatic control and safety protection coordination system.
6. Humidity is circulated using a stainless steel humidifier with surface evaporation.
7. Electrical equipment is executed using Schneider's product series, ensuring safety and stability.
