SCAA (Specialty Coffee Association of America) has produced eight series of visual color standard ground coffee classifications. Visual SCAA coffee standard for roasting classification.
Visual SCAA Roast coffee color standard, from "very light" to "very dark".
SCAA Project R4001 contains a lightweight black vinyl kit (10" x 12" x 1 3/4") which contains eight colour discs, numbered in increments of 10, ranging from "very light" (tile # 95) to "very dark" (Figure block #25).
SCAA visual grade reporting is inherently less accurate than using Hunter L, A, B or CIE L*, A *, B * color values and the associated SCAA coffee #. In order to get the best results with this visual coffee color evaluation system, professional color measurement equipment is required.
NR20XE spectrophotometer is a portable computer color meter designed by 45°/0° optical geometry structure. Its measurement diameter is 20mm, which is a large diameter instrument in the domestic color meter, and has a high measurement accuracy.
In the process of research and development, our scientists and engineers have measured various samples from dark to light, white to black, as well as the color test blocks provided by the International Organization for Standardization. The parameters tested are fully in line with international standards.
NR20XE can effectively eliminate the error between the eye and the colorimeter caused by the grain on the surface of the sample. So NR20XE is widely used in color QC department.
The hand-held spectrometer TS7700 ø8mm/4mm diameter can be switched freely, the platform/tip diameter can be easily switched, and it is suitable for various states of the tested samples such as coffee beans, coffee particles, coffee powder, and brewing coffee liquid, etc.
Equipped with high-end color management software, connected to the computer use, to achieve more functional expansion. The instrument has stable performance, accurate color measurement and powerful function. It is also widely used in color quality control of various products.
Table type spectrophotometer CS-800 is a high performance spectrophotometer with up calibers. The instrument adopts the D/8 illumination observation geometry recommended by the INTERNATIONAL Illumination Commission (CIE), and integrates the full-band LED composite light source, dual optical path splitter system, ETC real-time calibration and other technologies.
Solid samples (steel plate, cloth) can be directly placed on the measuring port, particles (tablets, color master particles), powder (pigment, coffee), paste (tomato sauce) can be placed in the petri dish, and then placed on the test port measurement.
