Special CR-410C version to measure the quality of coffee in various forms
The CR-410C handheld coffee colorimeter is specifically designed to measure the color of whole green beans, roasted beans, and roasted coffee using industry standard measurements.
The CR-410C coffee colorimeter easily and accurately measures the color of coffee in a variety of forms: whole green beans, roasted beans, roasted and lyophilized (Freeze Dried) coffee forms.
Without a colorimeter, coffee bean color measurement is conducted either visually or with bulky, expensive instruments. The CR-410C is a low-cost, portable option that uses the Specialty Coffee Association of Americas (SCAA) specialty coffee index to calculate the color, difference from a standard, roasted level (light, medium, medium dark, dark), and pass/fail information.
All other functions and features are identical with the standard CR-410.
