A summary plot of the matched Idronaut 305 Plus pH measurements and dye reference
pH for all field sites is shown in figure 18. The 305 Plus tracked changes in ambient pH at all
sites but the response factor (slope) and overall offset from the dye reference pH measurements
was different at each site.
