Hanna checker reagent interchangeable

[TvanB1]

I accidentally bought ULR phosphate reagent instead of the regular reagent. Wondering if these are interchangeable? I have the regular Phos checker, not the ULR. I know other checkers can use different reagents, not sure about this one.
TIA

I was told to make sure I purchase ulr for the ulr reader. Was told others would not give accurate readings.

The "regular" Hanna Phosphate HR has 2 reagents, "A", a liquid and "B" a powder packet labeled HI717B-0. Hanna ULR only has one reagent, a powder packet labeled HI774-0.
The powder for HR is Sodium Metabisulphate, while the powder for the ULR is Potassium Disulfate.

So, nope, they are not interchangeable.
