Hach® Aqua Chek 5 in 1 Water Quality Test Strips

Until now, testing of water was a cumbersome, time-consuming operation involving drop counting, test tubes, reagents, and color comparators. With these easy to use test strips, all of that is unnecessary. Gives you an accurate method of determining both total and free chlorine from 0-10 ppm, while Aqua Chek 5 tests for five water conditions simultaneously, measuring pH, alkalinity, hardness, free chlorine, and total chlorine with one strip.
