I haven't used this specific one, but I have used Hanna colorimeters/photometers in the past and been very satisfied.

Here is a list of all the Hanna-brand photometers:

Your largest cost will always end up being the reagents for the tests, so that should be something to take into account. It also helps when the reagents for your photometer are widely available and easy-to-find.

Looking at that site a meter like that could be very useful. . is there a lot of people using those?
Not to many I think, the Idea than we (our group) has is to buy one, A colorimeter should be a more acure reading,
if a 10 people group put $100 will buy the colorimeter and some regents, is in some way beter than but 250 dlls on test. And After that you can always leasing or rent it for new tanks to pay for it self.
Any one has more info about colorimeter?
Thank you

I own the thermo Orion Aq4000. They cost about 1000-1200 bucks. You need to be very mindful of the chloride/sulfate/magnesium/PH interference of saltwater. Nitrate is difficult to test for due to the chloride interference.
Make sure you look at each individual method your are interested in testing, they should give you a direction sheet for each parameter, and they will list what interferences there are.
I got mine because I recently built a greenhouse for coral propagation and thought it would be a good purchase. I found it for a reasonable price on ebay, and to be honest, I don't think I would purchase it again due to all of the interferences that mess up the tests. If your testing freshwater, I have no doubt it would be a wonderful purchase.

What is it that you want to measure?
these types of meters are popular for phosphate, although they may or may not be more accurate than the best kits.
But they are not going to be an especially accurate way to measure anything that is normally done by titration, which includes, alkalinity, calcium, and magnesium.
IMO, unless you have color perception issues, I wouldn't bother.

Thank you randy.
We would like to measure the basics, Amonia, nitrites, nitrates, Phosphates, Ca, Mag, Alk.
Most of all is we thougth than if a group puts together the cost, we could have a better readment. But is hard to find the reagens, and some colorimeters do not reag Mag, so we are going to be ending buying mag test. LOL
Thank you guys for all yours aportations.
