The research on the consistency of the testing accuracy for smoke measuring equipment based on ionization chamber principle

A convenient method is proposed here to determine the relative accuracy of measuring ionization chamber (MIC). A non-dimensional quantity is presented here to characterize the relative accuracy of the testing sample to the reference sample. There are two key points of the program. One is comparison by pairs. The other is eliminating the uncertainty in the program by exchanging the position and control unit in each testing group.
