An environmental test chamber is a device that simulates various natural or artificial environmental conditions such as temperature, humidity, light, and salt fog to test the performance and reliability of products. It is widely used in fields such as electronics, new energy, aerospace, and healthcare. Box structure: Made of high-strength and corrosion-resistant materials, it has excellent insulation and sealing performance. Refrigeration/Heating system: Temperature regulation is achieved through components such as compressors, condensers, and evaporators. Heating can be done using electric heating or heat pump technology, while cooling is based on the principle of heat absorption through phase change of refrigerants. Humidification/Dehumidification system: Humidification is generated by ultrasonic or electrode humidifiers, while dehumidification is achieved through cooling condensation or adsorption by desiccants. Some devices support humidity gradient control. Air circulation system: Composed of fans and optimized air ducts, it ensures uniform distribution of heated/cooling air, eliminates temperature dead zones, and improves the uniformity of the internal environment of the box. Intelligent control system: Integrated with sensors, microprocessors, and actuators, it continuously monitors parameters such as temperature and humidity.If you need more information about the models of our testing equipment.
