    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.
