A popular means of providing a cost-effective colorimetry solution for schools. It benefi ts from the robust Logbook design and is straightforward to use. It can be used as a stand-alone Colorimeter and is powered by a PP3 battery or external power supply.

When connected to a ScienceScope or Philip Harris datalogger, it can be used as a sensor for use withDatadisc software.

Auto-calibration occurs at the touch of a button, and the Colorimeter uses the standard cuvette size. A range of preset wavelengths can be selected, using LED technology to provide 6 spectral bands without filters or moving parts.
