Hanna p04

[Reef man 89]

looking to get a Hanna po4 checker which one do you guys recommend ultra low or just low. I have the dkh one already and love it. Any thoughts on this matter would be great. Anyone have problems with them? Are they acrute? right now I have the Api and hate it. Don't believe it right.if u don't recommend it what test do you recommend.

I have the low, 713. It works. As for accuracy, it's as accurate as anything else digital. There is a standard solution you can test the accuracy with. However, the test states that a reading in the range of .92 to 1.08 is acceptable. Mine was 1.03. The standard solution is 1ppm.

Which one to get depends on your current Phosphate level.

Go with the ULR 736

Hello all, thanks for your support, please find our conversion table for phosphorus parts-per-billion to phosphate parts-per-million. The conversion is multiply ppb Phosphorus by 3.066 then divide by 1000 to get ppm phosphates.

Thank you for choosing Hanna Instruments for your testing needs!

If you have your Phosphates in check and are trying to dial them in, go with the ULR. The LR would be better if you are in a higher range and/or not as picky.
