Open Colorimeter

The Open Colorimeter, designed by IO Rodeo, is a single-wavelength photometer for measuring visible/IR light absorbance through samples in a standard 10mm pathlength cuvette. 

The device uses the  Adafruit TSL2591 Light Sensor and a PyBadge pre-programmed with open source CircuitPython firmware. The cuvette holder and enclosure are made from 3D-printed black plastic. Links to the hardware designs and open source firmware are in the IO Rodeo Product Guide.

The Open Colorimeter ships pre-programmed & ready-to-use. No assembly, soldering or programming is required.
