Colorimeter

The Colorimeter is great for Beer’s law experiments, determining the concentration of unknown solutions, or studying changes in concentration vs. time.

Description

This 4-wavelength Colorimeter measures the amount of light transmitted through a sample at a user-selectable wavelength in order to determine the concentration of a solution. Features such as automatic sensor identification and one-step calibration make this sensor easy to use.
