LS175 is a handheld 45°/0° Illumination geometry colorimeter with a large 20mm measuring aperture, a 3.5-inch IPS color display and capacity touch panel, can connect with mobile phone or PC. Boasted with its color comparison and color scan functions, this device is applicable to color measurement on textured materials such as textiles, leather, wood furniture and meat, etc.. Compared with LS170 and LS171, this device can work independently without connecting APP on mobile phone or PC software. Several color charts integrated helps matching the closest color number of scanned color in short time. The device also has color comparison function, support multiple methods of adding standard. Availability of setting threshold of color difference, flexibility of choosing color difference formulas ensures QC quick check. The device can connect APP on mobile phone via Bluetooth or connect PC software via USB cable, offering various functions of scanned color sharing, printing report, color data import and export.

Application Industries

LS175 has wide application in color measurement and management, product/ incoming material color difference quality check in industries of textiles, leather, wood furniture and meat, etc., as it can measure larger area with its large 20mm measuring aperture, it can acquire more even color data when measuring textured or rough surface materials. APP on mobile phone and PC software with various functions are optional.

Color scan and Color Compare function

Press “Color Scan”on the screen or press power supply to scan color and get result within 1 second. Two clicks can complete color comparison. Quality Control inspection function can be conducted in batch by defining threshold in QC mode. In this mode, color deviation on 3 Lab color channels will be prompted, offering reference for color toning.

Multiple color spaces and color difference formulas to match demands of various industries

Multiple color spaces as Lab\Lch\CMYK and color difference formulas optional to match various color scan demands of different industries

Equipped with APP and PC software, support bilingual system

The device is equipped with APP on mobile phone and PC software, covering operation system of Android, iOS and Windows for more powerful functions. It can switch between Chinese and English to meet requirements of different application scenes.
