Hanna ULR meter question.

Hey guys. Quick questions:

What are the part/reagent numbers for the Hanna ULR test?
Have you ever gotten readings that you felt were consistently too high?

I am using the Hanna ULR Phosphorus meter HI736 with HI736-25 reagent with HO25 batch number. Previously used HO06 batch number.

I get accurate and consistent readings. I tested against the D&D/Merck kit.

I know in the past there were some defective reagent batches...but they gave LOW readings...usually 0!

Havent come across one giving a high number though.

Oh, the first meter I got gave readings all over the place, well outside the margin of error...I returned this to Hanna UK who tested the unit as faulty and sent me a new unit with a fresh reagent batch. This is the unit I currently been using for around 2 years I think.
