Great info. I'll look into that brand.
You reminded me that I have a Hach PO4 test kit 0 to 50ppm and it uses has a reference wheel. The reagent packs are old.
Interpretation of color rendering kits is a must and IS open to interpretation.
I will say that API's Quality Control is horrible from kit to kit.
