The Liyi Temperature Humidity Test Equipment is designed for testing material characteristics of wires, skins, plastics, rubbers, and fabrics. Equipped with a special ventilation regulator to maintain fresh air circulation 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 with dual-side airflow regulators ensures exceptional internal temperature uniformity and stability.
