Hanna Checker

[The-Russ]

Has anyone tried the Hanna Checker to test PO4 or other elements they make the testers for?

Hi,

I'm using the PO4 Hanna checker, it's pretty good and easy. I have recently bought the iodine checker, but this is useless because the range is not precise enough (it measures in 0.1 instead of 0.01).

Regards,
Jasper

You should be using this one
For po4 is the phosphorus ulr  (hi736).
