Spectrophotometers and colorimeters

Whatever your product, we have the right measurement solution. Uniquely designed for the food industry, our spectrophotometers and colorimeters are uniquely designed to provide calculations in a number of color measurement scales; for example, L, a, b, APHA color, Gardner color scale, the ASTM E313 for yellowness index, and the CIE lab color scale of L*, a*, b*. This allows you to custom tailor your HunterLab color analyzer to meet your specific needs. Additionally there are other, more specific, color measurement values available, such as those for caramel, coffee, tomato color, and citrus color.

We provide products that measure color the way your eye sees it – critical for the food industry. HunterLab pioneered the 45/0 technology that gives the true measure of color and we are the only color measurement company that offers 45/0 technology in portable, bench, and on-line instrumentation.
