本试验机提供可控制、调整臭氧浓度及温度之环境，以测定试件之抗臭氧性能；采用紫外线吸收的方式，设计监控器，以执行系统臭氧浓度量测，具有测试无须使用化学药剂之优点，且操作简便，维护容易。 The tester is designed to provide an auto-controlled ozone concentration environment for determining the ozone resistance of rubber. It adopts the ultraviolet ray absorption principle and is based on the Beer-Lambert Law to inspect the ozone concentration without chemical. After setting the required ozone concentration and temperature on the touchscreen, PLC control system will maintain the set values. The auto measuring system of UV ray can continuously and rapidly calibrate ozone concen
