School Savers - Vernier COL-BTA Colorimeter

Vernier COL-BTA Colorimeter

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.
