Uncertainty analysis and evaluation of verification results of conductivity meter |
|
|
Abstract Firstly, the source of uncertainty of conductivity meter is analyzed and discussed in this paper.Than establishing the relevant mathematical model. The standard uncertainty of each component is evaluated. In the meantime, the uncertainty of synthetic standard and expanded uncertainty are also obtained. The specific uncertainty evaluation value is given to ensure the reliability and scientificity of the conductivity meter.
Key words Conductivity meter, Standard uncertainty, Reference error, Extended uncertainty
