Cobra SMARTsense Colorimeter - Sensor for measuring colours and turbidity 0 ... 100 % / 0 ... 400 NTU (Bluetooth + USB)

Simple. Intuitive. Measurement.

Perfect for student experiments.

Function and Applications
Cobra SMARTsense is the ideal solution for inexpensive digitalization of science teaching. The sensors connect wirelessly (Bluetooth) or wired (USB) directly to the student's digital end device (smartphone, tablet or desktop PC). Using the free and award-winning measureAPP measurement software for iOS, Android and Windows, measured values can be easily recorded and graphically displayed. If more evaluations are needed, the measureLAB measurement software for Windows and macOS can be used.

Use the colorimeter sensor to measure the transmittance or absorbance of samples at different wavelengths. In addition, turbidity, for example of water samples, can also be determined directly in this way.
