Ventilation-type aging testing chamber 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.
The oven used to study the rubber that is heated under the rotary mode in a fixed period. Tested 1 day at 70 ℃, theoretically equivalent to 6 months exposed to the outside atmosphere. The oven is equipped with motor-driven rotary disk, hot-air circulation system that ensure uniform distribution of temperature.
Accord with ASTM D5423-9（R2005）（Ⅱ-Type oven）and ASTMD 5374-93(2005) UL-1581、GB、VDE、JIS、IEC
1. TCM control system can make the amount of increase heat is equal to heat of los
2. With P.I.D automatic calculation function, precision temperature control
