Abstract: Conductivity meter is the main equipment for measuring the conductivity of liquid solution. The conductivity cell constant of the conductivity meter has a great influence on the accuracy of the measurement data. In this paper, based on JJG 376—2007 Electrolytic Conductivity Meters, the uncertainty generated in the measurement process of conductivity meter conductance cell constant is evaluated.

Keywords: conductivity meter; conductivity cell constant; uncertainty measurement

電導率儀是通過電化學測量方法測定電解質溶液電導率的儀器,在水質分析、污水處理、環(huán)境檢測和工農業(yè)生產等領域有著廣泛的應用[1-5]。(剩余1587字)
