  • Easy To Use Time Saver By Richard on 6/6/2016

    I have the marine version of this checker and actually bought this one for my son-in-law who does freshwater. The Hanna checkers are easy to use and most importantly, they eliminate the color matching and interpolation that goes along with that. It takes longer to get the materials out of the (nice) case than it does to run the test. Draw 10 ml of test sample; calibrate unit with it; add 1 ml of reagent; take the reading in a few seconds. Try it, you'll like it!
