ColorFlex EZ Spectrophotometer
ColorFlex EZ Spectrophotometer
ColorFlex EZ offers the advantage of 45º/0º design ensuring that you not only get your colors right - but perfect every time. It measures your sample the way the human eye does. It lets you see your colors exactly the way your customers do, not just in the lab but in the real world.
Easy-to-use. Compact. And Increased Performance. ColorFlex EZ Spectrophotometer gives you unsurpassed confidence and trust in your outcomes.
Offers sampling versatility to measure everything from opaque solids, liquids, powders, granules and pellets to translucent solids and liquids. It comes with expanded sample storage for 250 setups, product standards and tolerances and up to 2000 sample measurements. ColorFlex EZ’s smaller size requires very little benchtop space and it’s one-touch operation makes it easy to operate for all of your color measurement challenges.
ColorFlex EZ is also offered in custom models for these solution applications:
ColorFlex EZ Citrus is specifically designed to measure the color of fresh and concentrated orange, grapefruit, and lemon juice. Citrus color scales provided in firmware include: Citrus Number, Citrus Redness & Citrus Yellowness.
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.
