Hanna lr no3 and ulr po4 tester regents

Guys

I just made a boo boo and after testing my po4 to 0.08 and nitrates to 01.5 , i wanted to double check po4 because I didn’t expect that from 0.03 yesterday and the reactor running.

But, I used the no3 regent in the po4 reactor and got 1.45

Are the 2 colourometers the same?

They both use the 525 nm LED but it might just be a lucky coincident that the numbers come out close. Try measuring phosphate in the nitrate Checker.

Yeah I’ll give it a shot
