摘要
Abstract
The ozone concentration produced by the dynamic calibrator in one transmission period was tested and analyzed its stability.During one transmission period,conduct multi-point testing three times on the dynamic calibrator and draw the curve.The slope of the curve and the intercept meet the requirements,but the relative deviation changes greatly.Compare the relative errors of ozone concentration produced before the dynamic calibrator transmitted the value in 2013 and 2016,it is discovered that the overall relative error in 2016 is higher than that in 2013.The stability declines as the time of use increases.Track and test the changes of ozone concentration produced by dynamic calibrator in a particular period of time.In general,the dynamic calibrator begins to be unstable in four month.The stability of the dynamic calibrator declines as the time of use increases.It is suggested to increase the transmission frequency of the dynamic calibrator with long service time in the transmission period or conduct random inspection.关键词
