Are you tired of trying to interpret your test kits? Elos has come out with a new colorimeter to help you accurately testing your aquarium water parameters. A Colorimeter is an instrument that compares the amount of light that passes through a solution with the amount that passes through the pure â€œsolventâ€. So clear the unit, add the reagent, then the colorimeter will pass light through and process the results and display them to you. No word of an ETA of when these might be available in the United States, but we sure would like to have one.Â We expect this unit to be in the $500 range. Still this takes aÂ lot of the color matching work away, which is well worth the price.
