I'm looking for a test kit to measure low range phosphate... a test kit other than the Hanna Phosphorus ULR. I already have a Hanna ULR, but stomping on it is going to be the best thing for my health (reduce my blood pressure, relieve some headaches, lower my anxiety, etc.), plus destroying it will save me a lot of time. Since my ULR will be in pieces, I will need a new test kit (not another Hanna unless I can get one that waits at least 4-5 minutes before shutting-off, or one that uses a liquid regent like their alkalinity checker, or preferably both of these options).
I know I sound like I'm bashing the Hanna ULR... ok, I am, but I'm not the one who designed a digital test kit that shuts-off in 3 minutes when it takes 4 minutes to prepare the test sample so I accept no responsibility for my actions. All bashing aside, is there an alternative test kit that accurately measures low levels of phosphate that is also fairly easy to read?
