ColorFlex EZ Tomato Spectrophotometer
ColorFlex EZ Tomato Spectrophotometer
The easy-to-use ColorFlex EZ Tomato is specifically designed to accurately measure the color of tomato in its every processed form – paste/purée, sauce, ketchup, juice, as well as fresh tomatoes. This accuracy is achieved by using 45º/0º optical geometry, the only measurement technology proven to measure color the way the human eye sees it.
Easy-to-use. Compact. And Increased Performance. ColorFlex EZ Tomato 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 Tile, 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.
