    I have a spare Hanna multiparameter photometer(colorimeter) that is new, never used.

    http://www.hannainst.com/usa/prods2.cfm?id=030003&ProdCode=HI%2083200-01

    I also have most of the releavnt reagents for any aquarium question.

    Alk
    NH4 LR
    Cu
    Hardness(Ca and Mg)
    Fe
    Mn
    NO3 (0-30)
    PO4
    K+

    Perhaps more, not sure, but this is a close list, worth about 700$ of their own.

    1000$ gets both the reagents and the meter shipped.

    maybe I am interested!

    As you maybe know, i have a hanna multiparameter photometer for measuring PO4/ No3. (NO3 gives also a false positive reading when I OD trace elements, so I don't use it)
    But with my meter, I cannot measure trace elements.

    It could be interesting to measure Mn and Cu.
    Did you ever do this? does it give reliable readings? in the range that we want? (I guess so)

    I know, it is just a toy... but still since I have never measured the amounts of trace elements in my tank, it could be a way to tweak your TE dosage.

    looking forward to your reply!

    I've measured Cu more than any trace, mostly due to it being a weed control and algicide.
    Seems to work decently.
    Mn not much. I have not checked or ran a standard curve for these two.
    Interference is common with a number of parameters, but you can add certain chemicals to remove these interferring compounds.

    hmm.

    I read the manual....

    the accuracy for Mg is too low imo.
    the accuracy for Ca is borderline oke.

    I can already measure:
    NO3 (0-30)
    PO4
    K+

    the accuracy for Cu is also too low imo: 10 ug/l.

    measuring Mn seems oke.
    However, 1000 dollar is a bit much for me for a single parameter...

    I think I will pass this offer.
    (and maybe buy a Mn meter :cool: )

    greets,
