Color Disc Test Kits

Color discs use a visual comparison method (color matching) to determine concentration and are accurate, portable, and require no batteries. Simply add reagent, turn the wheel until the sample matches a reference color and concentration is displayed in a window.

Each Hach color disc test kit includes apparatus, reagents, and instructions - all in a rugged carrying case. Available parameters include chlorine, pH, iron, silica, nitrogen and more.
