ColorFlex EZ Tomato Spectrophotometer / Colorimeter HunterLab America

Easy-to-use. Compact. And Increased Performance. ColorFlex EZ Spectrophotometer gives you unsurpassed confidence and trust in your outcomes.

ColorFlex EZ Tomato is specifically designed to measure tomato color in its every processed form – paste/purée, sauce, ketchup, juice, as well as fresh tomatoes. Tomato color scales provided in firmware include: Tomato Paste Score (TPS), Tomato Sauce Score (TSS), Tomato Catsup Score (TCS), Tomato Juice Score (TJS), a/b ratio, Fresh Tomato Color Index (FTCI) & Lycopene index.

Hunter L,a,b color and CIE L*a*b* color, are also provided within the firmware, allowing for the capability to also use your ColorFlex EZ Tomato to measure the reflected color of a wide range of non-tomato samples - liquids, semisolids, powders, and solids. Inside its optional, custom designed, watertight carrying case will be everything you will need to immediately start measuring tomato color values, and includes: ColorFlex EZ Tomato instrument, Complete set of calibration & diagnostic tiles, HunterLab Tomato Reference Standard, 2 glass sample cups, Port insert for sample cup, Sample cup opaque cover and backed up by the finest customer support in the industry and USDA approved.
