Introduction to Calibration System of Water Quality Ozone Analyzer and Study on Traceability Method
The calibration system of ozone water quality analyzer was developed and its uncertainty was evalua-ted.The absorbance and molar absorbance coefficient of ozone water were determined by ultraviolet spectrophotome-ter and traced by iodine method.The results show that the stability of the system is 3％/10min,the extended uncer-tainty is 0.05mg/L,k=2,and it can be used for the calibration of the analyzer.
