New Question

[Donsreef]

I just got my Hanna Checker HI736 - Phosphorus Ultra Low Range Checker. How do I or do I convert something?
I did my first test and it read 106 ppb. Please help.

Looks like your at .32 ppm.

I found this formula online but have no idea if its accurate but use it anyway: (ppb x 3.066)/1000=ppm

Yes that is correct. Easier way to do it is your number(PPB) X 0.003066
