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

Function and Applications

Use the Cobra SMARTsense Colorimeter & Turbidity to measure the transmission or absorption of samples at different wavelengths and investigate the basic concepts of optical analysis of liquids with your pupils in a child’s play way.

With sampling rates of up to 1 Hz and a resolution of 0.1 % (or NTU), the digital colorimeter and turbidity sensor can be used flexibly in experiments where transmission, absorption or turbidity – for example of water samples – is of interest.

Connect the Cobra SMARTsense Colorimeter & Turbidity wirelessly via Bluetooth or wired via USB to the free and award-winning measuring software measureAPP – available for iOS, Android, Windows and Linux.

Switch on. Connect. Start measuring.
