摘要

为满足实验室纯水机内置在线监测仪表的现场校准需求,建立了一套由高精度电导率仪、总有机碳分析仪和可调流速缓冲装置组成的标准测量装置。通过将纯水机在线监测仪表的测量结果与标准测量装置的测量结果进行比较,实现了纯水机在线电导率/电阻率和总有机碳监测仪表的现场校准。对11家实验室纯水机进行现场试验和分析。结果表明:纯水机在线电导率仪器相对示值误差在-2.4%～15%,测量扩展不确定度为1.7%(k=2);总有机碳仪器相对示值误差为-98%～125%,测量扩展不确定度为4.8%(k=2)。

Abstract

To meet with the needs of on-site calibration of monitoring instruments installed in pure water machines, a measurement standard system including high-precision conductivity meter, total organic carbon analyzer and adjustable flow buffer device has been developed.By comparing the indication values of built-in monitoring instruments of pure water machines with the measurement results of the measurement standard system, the on-site calibration of conductivity or resistivity meter and total organic carbon analyzer installed in pure water machines was achieved.The experimental results of eleven pure water machines showed the indication errors of built-in conductivity or resistivity meters ranging from -2.4% to 15% with the expanded uncertainty of 1.7% (k=2) and those of built-in total organic carbon analyzer ranging from -98% to 125% with the expanded uncertainty of 4.8% (k=2).
