![]() 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.
