Colour discs use a visual comparison method (colour matching) to determine concentration. Simply add reagents to the sample, turn the wheel until the sample matches a reference colour - concentration is displayed in a window.

Each Hach colour disc test kit includes apparatus, reagents, and instructions - all in a rugged carrying case. Available parameters include Chlorine, pH, Iron, Silica, Nitrogen and more.
