Hot air aging test chamber

Product technical parameters：

BZ-HQ-2 Hot air aging test chamber specification：

The machine is used to test aging, elongation, tension of rubber, plastic, artificial leather and other chemical synthetic products. The horizontal forced air circulation system and the air flow adjusting plates on both sides of the inner side ensure the uniform and stable internal temperature of the testing machine. Refer to ASTM, JIS, GB and other test specifications.
