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.
