Color Comparator Demo - Iron Test

Color Disc Comparators are designed to react with a wide range of specific chemicals such as iron, chlorine, fluoride, and nitrates. They are used with a range of interchangeable colour discs for specific chemicals. The test uses a visual comparison of a reacted sample colour to a colour disc standard to determine the concentration of the chemical in the test sample.

This demo shows how to use a color comparator to measure iron levels in water.
