The HI 713 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, Place the vial into the HI 713 Checker®HC, press the button and read the results. It’s that easy.

Easier to use and more accurate than chemical test kits

Also nobody knows if it's any good or not, Digital equipment generally is only as good as it's calibration.

Still could be better than a test kit. I don't know about you guys but on most test kits matching the colour from the test to the results is 9 times out of 10 a pure guess. Its always a "slightly darker than that but lighter than that one" which in real terms is a huge margin for error. The only test kits I find reliable in know what the results are giving is the ones like calcium kits where you add a couple of drops of regent at a time until it changes colour (not saying they are accurate either, just easier to read).

Something like this looks like a good idea to me and if the +/- 4% accuracy they state is correct its going to be a whole lot more accurate then a normal test kit where you have to play match the colour.
