The Wireless Colorimeter and Turbidity Sensor simultaneously measure the absorbance and transmittance of six different wavelengths. Each wavelength represents a region of the ROYGBIV color wheel and can be displayed graphically using PASCO software. The colorimeter can be used to study concentrations of solutions, the rates of chemical reactions and more. The Wireless Colorimeter and Turbidity Sensor are also resistant to splashes and spills, ensuring years of use in labs. It was also designed to draw minimal amounts of power which give it a long battery life and reduces how often it needs to be recharged. Calibration is also fast and easy, eliminating wasted time during the lab activity.
