I. Applications of High and Low Temperature Humidity Test Chambers
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 humid and wet conditions during storage, transportation, and use. The test equipment is mainly used to simulate environmental conditions for products according to national standards or customer-defined requirements, assessing the physical and other related properties of the products under high and low temperature conditions. 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.

Section 4: Structural Characteristics of the Equipment
1. The equipment is mainly composed of the housing, refrigeration system, air circulation system, and control system.
2. The housing is made of cold-rolled steel plates with double-sided electrostatic spraying, and the inner lining is constructed from SUS304 stainless steel plates. The door features a large observation window in the center, equipped with an observation light, allowing users to clearly view the test conditions of the sample.
3. The overall appearance is aesthetically pleasing and generous. The thermal insulation layer is ultra-fine glass wool, offering high strength and excellent thermal insulation properties.
4. The equipment primarily uses an intelligent digital temperature and humidity controller, which is easy to learn and operate, and different functional levels of instruments are interoperable. The input features a digital calibration system, with built-in non-linear correction tables for common thermocouples and thermistors, ensuring stable measurements. Equipped with on/off and PID artificial intelligence adjustment functions, with 0.1 grade accuracy and multiple alarm modes. Features independent heating and cooling, and a unique BTHC balanced temperature control 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 by evaporative means using a surface of stainless steel humidifier.
7. Electrical appliances are executed using Schneider's product series, ensuring safety and stability.
