Is this the right reagent?

I got my Hanna phosphate ULR checker used and had been using this reagents. I took a closer look and the reagent says “LR” so is that mean with all the tastings I have done are false? Or what?

That is the incorrect reagent, I have bought the wrong ones before but never used them as Hanna said they are incorrect in a post somewhere and will not provide proper results. Maybe somebody else has tried

Dang it! I found some expired ULR reagents and tested which kinda of close to the “wrong” reagents. I usually tested with the LR at around .29. Today I dosed phosphate RX at 50% strength and I just tested with the expired ULR yield .17

so, it seems works but maybe not as accurate
