![]() Does anyone know why it seems that the Hanna Phosphate ULR Checker HI774 seems to be tough to find now (in Canada)? Is it being phased out? I was going to get one, but if there is a change coming, I may hold off. Anyone have any useful info on this? Should I be concerned, or just a supply hiccup? Seems many Cdn online places don't even have it listed.

![]() I prefer the Hanna HI736 ULR Phosphorus unit
When using the Hanna Phosphorus to Phosphate conversion chart the 736 gives the equivalent of the 774 with a third decimal place |
