Single and Dual Input Analyzers for Low Level Conductivity

Calculations

A range of computed dual conductivity readings can be displayed, each showing the result of a calculation performed by the analyzer.
In each case, the type of calculation is shown on the lower display line, followed by the result of the calculation.

Calculations performed are:

Difference 

=  A - B

% Rejection  =  (1-B/A) x 100
% Passage  =  B/A x 100
Ratio = 

A/B

Inferred pH 

=  Uses an algorithm to calculate the pH value of the solution, inferred from its conductivity, 

in the range 7.00 to 11.00 pH. see appendix A.3 on page 75 for further information on inferred pH.

Note.

If the analyzer is used with a cation resin column, Sensor A must be installed before the column and Sensor B after the 

column for the calculations, especially inferred pH, to be correct.
