MULTICHANNEL OZONE-MEASURING APPARATUS

摘要

The present invention relates to an ozone-measuring apparatus which measures the ozone concentration and a variation in the ozone concentration of a predetermined space. More particularly, the present invention relates to a multichannel ozone-measuring apparatus, which performs measurements of low-concentration ozone to high-concentration ozone at the same time by means of a single ultraviolet lamp using an ultraviolet absorption method.
