Not quite right. ULR Phosphate (HI774) is PPM. ULR Phosphorus (HI736) is PPB.The ULR is measured in PPB instead of PPM.
You need this fine detail for this test.
I use HI774.

What’s the difference?

Yeah tbh the time scale doesn’t really bother me it’s just matching the colours up on some tests that is pretty much impossible and your just guessing at the actually readI'm a big hannah guy - I have ALK/CAL/Nitrate currently and plan on picking up a ULR phosphate as well.
To me, despite the longer time to run a test, once you have a solid repeatable methodology (especially for the powder based tests), you can't beat the accuracy and ease of testing.
yeah I just been looking at that also onlyHuh? My phosphate ULR measures in PPM.
I have a model #HI774 ULR checker.

So which is best ?Not quite right. ULR Phosphate (HI774) is PPM. ULR Phosphorus (HI736) is PPB.
I use HI774.
HI774So which is best ?
This post describes the difference between 774 and 736. 736 is more accurate closer to zero.So which is best ?
Cheers anyone else clarify this before I take the plunge ?I think it would show an out of range error. I didn’t care about this because I don’t want to be near .9ppm anyway.
