NEW Vernier Software & Technology Colorimeter COL-BTA

Surplus unused equipment from the University of Tennessee,this listing is for aNEW Vernier Software & TechnologyColorimeter Model# COL-BTA / MSRP $128.00The Colorimeter is great for Beer’s law experiments, determining the concentration of unknown solutions,or studying changes in concentration vs. time.
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.
