Description
Easy-to-use. Compact. And Increased Performance. ColorFlex EZ Coffee Spectrophotometer gives you unsurpassed confidence and trust in your outcomes.
The easy-to-use ColorFlex EZ Coffee is specifically built to meet and exceed your needs in measuring the color of roasted coffee grounds. It makes it easy to define the degree of roasting. Coffee color scales provided in firmware include: HunterLab Coffee Color Index (HCCI), SCAA Number & SCAA Roast Classification.
The ColorFlex EZ Coffee provides the measurement data needed to ensure consistent batch-to-batch production quality. Coffee color scales provided in firmware include: HunterLab Coffee Color Index (HCCI), SCAA Number & SCAA Roast Classification. In addition to its specialized coffee measuring ability, the ColorFlex EZ Coffee can also measure the reflected color of a wide range of non-coffee samples – liquids, semi-solids, powders, and solids using standard Hunter L,a,b color and CIE L*a*b* colorimetric and spectral data indices. Every ColorFlex EZ Coffee instrument is ready to immediately start measuring coffee color values, and includes: ColorFlex EZ Coffee instrument, Complete set of calibration & diagnostic tiles, Coffee tile for performance qualification, 1 sleeve of plastic coffee sample dishes and backed up by the finest customer support in the industry.
