摘　　要：JJG 757—2018《实验室离子计》检定规程适用于电极电位法测量溶液中离子活度的实验室通用离子计的检定。钠离子计可以依据此规程进行校准。本文重点从校准参数、校准程序、标准物质的选择、标准溶液的配置等方面进行分析,并对测量结果的不确定度进行评定。The verification regulation of JJG 757—2018 Laboratory ion meters is applicable to the verification of general laboratory ion meter for measuring ion activity in solution by electrode potential method. The sodium ion meter can be calibrated according to this procedure. This paper focuses on the analysis of calibration parameters,calibration procedures,the selection of reference materials and the configuration of standard solutions,and evaluates the uncertainty of measurement results.
