Understanding Hanna checker readings

[The Grizz]

Does anyone know where to find a chart that tells you what is a normal reading from all the different Hanna checkers?

not yet-i've been searching for quite a while.calcium is no problem,but the other 3 i would like to know their conversions

I know from talking from Steve @ RCE that the normal or safe reading for Phos should be .00 - .03
