Five major characteristics

LS173 is a portable multifunctional colorimeter with D/8° (SCI) optical geometry design. The color analyzer is equipped with a 3.5-inch IPS color capacitive touch screen, providing an excellent operating experience. The colorimeter integrates multiple natural color charts, and can quickly match the measured color to the closest color codes. The color difference meter also has a color difference comparison function, supports a variety of standard color addition methods, the color difference threshold can be set. The color difference formula can be flexibly selected, which can realize rapid QC testing. 


LS173 usually used in paint, metal, stone, ceramic tiles and plastics industries for color measurement and management, color difference quality control. The colorimeter is illuminated by an integrating sphere diffused light source, which is very suitable for color measurement of high-gloss samples.
