4 Overview
The ozone aging test chamber is mainly used to simulate and strengthen ozone conditions in the atmosphere, and to study the effect of ozone on rubber, plastic and other materials.
It is an equipment that can quickly identify and evaluate the anti-ozone aging performance of materials based on the law of action. It is mainly controlled by the ozone concentration system
system, temperature and humidity control system and work space. Ozone concentration control systems generally use high-voltage discharge or ultraviolet irradiation
