Hannah phosphate checke

[Wildreefs]

I have the hanna checker, not ultra low range. I picked up testing reagent today, and I see they are the ultra low reagent packets.

are these ultra low range packets usable in regular checker?

You need to match the reagent# to the model#

HI713 phosphate checker uses HI713-25
HI774 phosphate ULR uses HI774-25
HI736 phosphorus ULR uses HI736-25

Reagents follow the model# but can end in 0 (zero)
Reagents are designed for each checker.

You will get a test result that is very close. If you can’t return the box, use them. Both @Rick Mathew and I have switched both Checkers and both chemistry packets and obtained nearly the same test results for all the wrong combinations.

Ok, I will get the others, in the mean time I used 2, level is 2.04 );
