摘　　要：水质监测在环境监测中占据重要地位,其中色度是该监测中的一项重要指标。色度仪是根据铂-钴比色法测量水质色度的仪器,铂-钴色度仪与水质色度仪的原理相同。为保证色度测量结果的准确性,需保证其量值的稳定性,进行量值溯源,并选择合适的国家标准。现行的色度仪计量的国家标准有JJF1947-2021《铂-钴色度仪校准规范》和JJF1689-2018《水质色度仪校准规范》,本文对其测量范围、原理、计量特性、标准器和测量方法等异同进行了归纳分析。Water quality monitoring plays an important role in env ironmental monitoring,among which chroma is an important index.Colorimeter is based on platinum-cobalt colorimeter to measure water colorimeter,platinum-co-balt colorimeter and water colorimeter principle is the same.In order to ensure the accuracy of chrominance meas-urement results,it is necessary to ensure the stability of the measurement value,carry out the measurement value traceability,and select the appropriate national standard.The curent national standards for colorimeter measure-ment include JJF 1947-2021"Calibration Code for Platino-Cobalt Colorimeter"and JJF 1689-2018"Calibra-tion Code for Water Colorimeter".This paper summarizes and analyzes the differences and similarities of their meas-uring range,principle,measuring characteristics,standard and measuring methods.
