What’s the difference?
The ULR is measured in PPB instead of PPM.
You need this fine detail for this test.
ULR Phosphate Checker Specifications:
|Range:||0.00 to 0.90 ppm|
|Accuracy 77° F / 25° C:||±0.02 ppm ±5% of reading|
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 only
This post describes the difference between 774 and 736. 736 is more accurate closer to zero.So which is best ?
