LS173B — a portable multifunctional colorimeter adopts D/8° optical geometry design. The digital colorimeter is equipped with a 3.5-inch IPS color capacitive touch screen, providing an excellent operating experience.

The instrument integrates multiple natural color charts, and can quickly match the measured color to the closest color code. The colorimeter also has a color comparison function and supports a variety of standard color addition methods. The color difference threshold can be set, and the color difference formula can be flexibly selected, which can realize rapid QC testing.


LS173B adopts D/8° specular component include (SCI). Usually used in automotive paint, metal processing, stone, decorative materials, plastics industries for color measurement and management, color difference quality control. The color difference meter is illuminated by an integrating sphere diffused light source, which is very suitable for color measurement of high-gloss materials.
