1. Brief Introduction of Spectrophotometer CS-580 Our spectrophotometers adopt high technology from overseas. It tests based on the condition of D/8 that is internationally used. Our device is widely used for color testing for any industry especially for painting, textile, plastic cement, food, building material and other productsâ?? color quality control. It could connect with color matching software. 2.Advantages of our Spectrophotometer CS-580 1).Obtained Metrology Accreditation Certificate in China 2).Large data storage space 3).Large TFT display screen 4).Modern and fashionable design based on human engineering 5).Easy to operate and compact operation interface 6).Pre-locating panel design for easy instrument calibration 7).Uses LED light source; high capacity rechargeable lithium-ion battery 8).Can measure both SCI(specular included)and SCE(specular excluded) at the same time 9).Includes PC software to manage data 10).Can connect to micro-printers for printing 3. Spectrophotometer Longest Guarantee Time a. One Year Guarantee Time. b. If testing data is not correct, we can do refund. c. We will provide testing report for every device to assure the authority of the data and it will save the calibration cost for 1 year. 4.
