Liyi Constant Temperature and Humidity Control Test Cabinet
The Liyi climatic change temperature and humidity chamber is designed for testing material characteristics of wires, skins, plastics, rubbers, and fabrics. Equipped with a special ventilation regulator to maintain fresh air during heating, this testing machine features sophisticated air-displacement adjustment and digital monitoring of voltage, current, watt-hours, and timing for precise air replacement rate measurement. The horizontal circulatory air supply system and dual-side airflow regulators ensure uniform and stable internal temperature distribution.
