Colorimeters & Photometers

Colorimeters and Photometers are used to analyze samples of water by adding a chemical reagent that reacts with the substance being analyzed and changes its color. The colorimeter then monitors the light transmission through the water samples to determine the presence and quantity of the substance of interest.

The chief advantage of colorimetric analysis is that it provides a simple means of determining minute quantities of substances.
