Hanna P04 Ultra low question.
Just ran my Hanna P04 tester and got a reading of "0.00" that's ok as last was .04 Now just tried my Hanna Ultra Low P04 test for the first time and the reading was simply "5" in the far right side of the window. So what does that mean .005? I would have thought I should have seen a decimal place in there? Only ran the test once as I only have the 6 reagents.

Doesn't that meter read in parts per billion? So wouldn't that be 5 ppb ? The regular phosphate reads parts per million (ppm) and I've seen that give me non decimal values.

The ULR actually reads phosphorous (P), not phosphate (PO4) - to convert to a ppm PO4 reading, you multiply the reading by 3.066 then divide by 1000. So a reading of 5 should be something like 0.01533 PO4.
