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
