What is a Colorimeter?

A colorimeter is a light-sensing instrument that measures how light is absorbed and transmitted as it moves through a liquid sample.

Colorimeters follow the principles of the Beer-Lambert Law (Beer’s Law), which is the linear relationship between absorbance and concentration.

To analyze a specific analyte in a liquid sample, color-forming reagents are added. The color reaction is proportional to the concentration of the analyte.

High concentrations will absorb more of the light than a solution with a diluted concentration.

Types of Colorimeters

Hach’s easy-to-use, robust, portable colorimeters are built to handle the unique stresses present in testing water quality.

Whether you are looking for a single parameter testing device or sophisticated multiparameter handheld colorimeters, Hach has a solution that will support your needs, with quality reagents and simple testing procedures.
