The feature video about LS176B spectrophotometer

The LS176B is a portable spectrophotome with a 3.5 inch IPS color capacitive touch screen for an excellent experience. The instrument integrates many color cards, which can be matched to the nearest color card number for the sample color. It also has a color comparison function, a variety of color difference formulas to choose from, allowing for quick QC testing. Sharing the color data by connecting to the mobile app through Bluetooth or to the PC software via USB port can meet the different needs.

The instrument employs full spectrum LED light source and spectral sensor, adopting D/8 illumination geometry with high measurement accuracy. It is widely used in the industries of automotive paint, hardware processing, stone, decorative materials, and plastic.
