Multiparameter Photometer?

[Oats]

Anyone have experience using the Hanna Instruments 83200-2008 or something similar? Would this even be useful? I am not sure how the ranges available correlate to the values we are interested in here. Opinions Please!

 

Issues I see, unless the units are not the same used in test kits, which I do not know:

Magnesium test 0 to 150mg/L

Calcium 0 to 400mg/L

Potassium MR 0 to 100mg/L

Alkalinity/Hardness values

(based on sample values from aquariumwatertesting.com aqwatertesting sample)

mg/L and μg/L are approximately the same units as ppm and ppb, respectively, in water.

Thanks, sounds like it wouldn't work well then if it will only test up to 150 ppm magnesium and 400 ppm calcium.

got some locals with some Hanna Instruments. besides the fact they dont require any mixing and shaking and measuring, they are just over priced for this hobby and you do not need such an exact measurement. just imagine how many boxes of salifert test kits you can buy with it.
