I. The Application of Constant Temperature and Humidity Test Chambers
The equipment is primarily designed for electrical engineers, electronic products, their components, and other materials to test their adaptability to storage, transportation, and use under high and low temperature, as well as humid and wet conditions. This testing equipment is mainly used to simulate environmental conditions in accordance with national standards or customer-defined requirements, to assess the physical and other related properties of 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.

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 outer shell of the box is made of SUS304 stainless steel embossed sheet or Baosteel cold-rolled steel plate with electrostatic powder coating, while the inner lining is constructed from SUS304 stainless steel plate. The door features a large observation window in the middle, equipped with an observation light, allowing users to clearly view the test conditions of the samples.
3. The overall appearance is aesthetically pleasing and generous. The insulation layer is ultra-fine glass wool, featuring high strength and excellent thermal insulation properties.
4. The main temperature controller for this equipment is an intelligent digital temperature and humidity controller, easy to learn and operate, with different function level instruments compatible with each other. The input features a digital calibration system, with built-in common thermocouple and thermal resistance non-linear calibration tables for stable measurement. Equipped with on-off control and AI artificial intelligence adjustment functions, 0.2-grade accuracy, and multiple alarm modes. Features independent heating and cooling, and a unique BTHC balanced temperature control method.
5. The refrigeration system employs a fully enclosed imported reciprocating compressor set from Europe's TAIKANG, featuring mechanical single-stage refrigeration or a cascade low-temperature circuit system, with an automatic control and safety protection coordination system.
6. Humidity is circulated by the surface evaporation of a stainless steel humidifier.
7. Electrical appliances are executed using Schneider's product series, ensuring safety and stability.
