Ozone Automatic Monitors Based on Ultraviolet Spectrophotometry and Relevant Standard Transfer Methods

With the rapid growth of economy and the accelerating of urbanization process, photochemical pollution caused by ozone has become a hot spot in atmospheric environment protection field. Automatic monitoring of ozone is essential for both environment management and scientific research. This study introduced the ozone automated monitor and its quantity traceability system, focusing on interference factors during monitoring and standard transfer methods. It was proved by experiments that the output of ozone calibrator with photometer showed better stability.
