Overview
The LS177 large aperture spectroscopic color difference meter adopts D/8 illumination mode and has a large test aperture of 50mm, which is specially used for Color and color difference measurement of non-transparent materials such as powders and particles. The instrument has a variety of Color spaces and Color parameters, and can also display Light spectrum reflectance Linear dispersion, which is widely used in Color management and quality control in Coatings, Plastics, Food, Medicine and other fields. The instrument is also equipped with professional mobile app and PC software to support data export and report printing.
Features
1. The measurement diameter is up to 50mm, especially suitable for the color difference measurement of uneven objects such as Masterbatch, powder, coarse cloth, etc.
2. Using Full Light spectrum LED Illuminant and Advanced Light spectrum Sensor, providing professional Light spectrum reflectance Linear dispersion, providing more professional Color data for Color measurement, from which to obtain Hue, Saturation, depth and other information.
3. High Accuracy, High Repeatability, Standard Deviation Delta E * ab ≤ 0.03, in line with national first-class metrology standards.
4. Give a special sample container, which can be used for the measurement of Masterbatch, powder, opaque liquid and other materials.
5. With QC detection function, you can set the color difference threshold by yourself, and the instrument automatically judges whether the color difference is qualified.
6. Color parameters of measurement include CIE Lab, LCh, Luv, Yxy, CMYK, RGB, yellowness-98, whiteness-98, whiteness-Gauz, whiteness-Hunter, whiteness-R457, Light spectrum reflectance and other parameters.
7. The instrument has built-in multi-industry common electronic Color Chart, Color measurement can quickly match the closest Color Chart number, Color Chart matching accuracy is greater than 90%.
8. With the 7-inch color Touchscreen, only two points can be used to measure color difference, and the operation is very simple.
9. You can connect to the APP to realize Color sharing on the APP. With PC software, it has stronger color difference statistical analysis function, and can import and export instrument storage data.
Principle
The instrument adopts D/8 illumination mode, including specular reflection light (SCI), using full light spectrum LED Illuminant, Wavelength range 400-700nm, wavelength interval 10nm. Light spectrum reflectance Linear dispersion of the sample is captured by the advanced Light spectrum Sensor, and analyzed under Illuminant D65 and 10 ° field of view to calculate various Color space and color difference parameters.
Applications
Coatings, plastics, food, pharmaceuticals
