Liyi Constant Temperature Humidity Stability Environmental Test
Chamber
Liyi Climatic Chamber is used to test the material characteristic for
wire type, skin type, plastic, rubber, cloth, Equiped with a
special ventilation regulator for maintain the fresh air inside
when heating. This testing machine design with sophisticated
air-displacement adjustment device and a digital voltage meter,
current meter, watt-hours, the timer can be used to measure the air
replacement rate. Horizontal circulatory air supply system and both
sides of airflow regulator to ensure the internal temperature
uniformity and stability.
