How are you measuring the free and total chlorine residuals ? Amperometric or dpd? Pressure and pH will affect how accurate amperometric probes read and will affect free and total probes differently.

HACH makes a few different varieties. The cl10 is their amperometric probes (which don't use reagents) . The cl17 is their dpd flow through monitor and it uses quite a bit of reagent.

Am using HACH chloro meter to measure free and total chlorine. residual chlorine is the results from total chlorine - free chlorine.
