Don't let that gizmo stop you from ordering a K-2006. The FAS-DPD titration test will give you accurate, repeatable (useful) readings. Maybe you could do a comparison and let us know how well it works.

OK. I did my tests last night and here are the results. YES i added 1 chlorine tab (Trichloro-s-triazinetrione), when i get home im gonna test again and remove the tab and add liquid, we have 500 gallon totes of the stuff here at work.

HACH: .8 TC, .9 FC, .1 CC.
TAYLOR: 1-2 Cl, .5-1 CC, 7.7 PH, 120 TA.
ULTRAMETER II: 7.49 PH.
