Re: N-P-K electronic test kit?

ISE electrodes do exist for NO3, NH4.
PO4 is a bit tougher, so is K+.

They do make colormetric kits, such as the Hanna monitors. These run about 175$ea and do not include reagents.

They make a multiparameter unit etc as well, for about 800$.

But, like the probes, you need to calibrate them to make sure they are accurate.

Aquaticeco.com seesm to have most things, also, Ben meadows.

This is for the Lamott/Electronic stuff.

For cheapy stuff, most on line places carry the rest.
