LS177C Coffee Colorimeter
Measuring SCAA, roast degree, color difference comparison of coffee beans
Equipped with 7-inch touch screen, easy to use
One-touch measurement of SCAA, HCCI and roast degree
50mm large test aperture
Lab value and color differrence comparison of coffee beans measurement
LS177C is a coffee colorimeter. It has a 7-inch touch screen, which is easy to use. The instrument can quickly match the closest SCAA number and HCCI to the measured coffee beans, and display the relevant coffee roast level. It also has color difference comparison function and color difference threshold can be set to achieve rapid QC testing. The instrument is equipped with mobile APP and PC software to facilitate color management of coffee beans. The instrument uses full-spectrum LED light source and advanced spectral sensor. It can pass the test of authoritative metrology institute.
