Test strips are one of the easiest methods of testing water. Simply dip the strip in water, following the instructions and compare the color of the strip to determine the result. Use test strips when a general range is sufficient. Test strips should not be used when an exact measurement is required.

With Hach Water Quality Test Strips, technicians in the field can test many samples in only a few minutes, and make immediate evaluations on-site. No measuring, set-up, clean-up, or chemical handling are necessary. Hach test strips are also used in laboratories all over the world for pre-test screening-to detect the presence of materials that might interfere with lab testing.
