The HunterLab ColorFlex Tomato Color Meter system has met the criteria set by the USDA for the evaluation of color in tomato products in accordance with the U.S. standards for grades of tomato paste, tomato sauce, tomato catsup and tomato juice. As recommended by the USDA, the ColorFlex Tomato Meter's standard for scores is traceable to the UC-Davis master standard. The Tomato Meter eliminates subjectivity of visual methods and gives reproducible objective measurements. In practice the tomato sample is poured or spooned into a sample cup. The cup is placed onto the instrument measurement port. By pressing one button on the instrument the measurement is made. TJ (Juice Score), TK (Catsup Score), TP (Paste Score), TS (Sauce Score) or AB (a/b ratio) will be displayed. The Tomato Meter can be connected to a printer if hard-copy data is desired.

The ColorFlex Citrus Color Meter system is for the measurement of citrus color, as it measures the Citrus Number, Citrus Redness and Citrus Yellowness. These indices were primarily intended to score orange juice concentrate, but in practice have also been used for grapefruit and lemon juice. The ColorFlex Citrus Meter eliminates the subjectivity of visual methods and gives reproducible objective measurements. In practice the citrus juice sample is poured into a 1"-diameter glass test tube. The test tube is inserted into the tube holder. By pressing one button on the instrument the measurement is made. CN (Citrus Number), CR (Citrus Red) and CY (Citrus Yellow) will simultaneously be displayed. The ColorFlex Citrus Meter can be connected to a printer if hard-copy data is desired.
