Overview
The LS175 is a Handheld large-diameter color difference meter designed with 45 °/0 ° Optical inspection geometry. It adopts a 20mm measurement diameter, which is very suitable for color difference comparison and Color measurement of textured or rough materials. Equipped with a 3.5-inch color large Touchscreen, the instrument can be used alone, and the operation experience is good. There are multiple standard Color Charts integrated inside, which can quickly match the color measurement to the closest Color Chart number.
LS175 is widely used, with a large measurement diameter of 20mm, a larger sampling light spot, and can measure a larger area of materials at one time. For the measurement of textured and rough objects, it can obtain more uniform Color data. At the same time, it is equipped with functional mobile end APP and PC software; it is usually used in product Color measurement and management, product color difference quality control, batch inspection of incoming materials in clothing fabrics, leather products, wood furniture, meat food and other industries.

Principle
The LS175 color difference meter is designed with a 45 °/0 ° Optical inspection geometry, that is, a 45 ° annular illumination, 0 ° reception Measurement mode. The instrument uses a full Light spectrum LED Illuminant with a Wavelength range of 400-700nm. Light spectrum data of sample reflection is collected through a chip-scale color Sensor. Color measurement and analysis are performed under D65 Illuminant and 10 ° Field of View conditions.
Applications
Color measurement and management of products in clothing fabrics, leather products, wood furniture, meat food and other industries, product color difference quality control, batch inspection of incoming materials
