Overview
The CHNSPEC CS-421 color difference meter is a professional version of the color measurement instrument, equipped with a built-in camera for accurate positioning measurement, integrated UV Illuminant supports fluorescent color measurement. By connecting to the mobile app, data measurement, storage, color scheme and color correction functions can be realized, and multiple sets of color card information are built to facilitate the search for similar colors. This model has a measurement diameter of 4mm and is suitable for small size samples.
Features
1. Automatic calibration function, easy to operate
2. SCI/SCE Measurement mode, Gloss can be removed, consistent with human eye perception
3. Support more than 30 measurement indicators such as hiding power, whiteness and yellowness
4. Provide 26 Illuminant Evaluation Conditions
5. Repeatability, stable measurement, Standard Deviation Delta E * ab ≤ 0.06
6. Guaranteed metrology authentication
7. Built-in massive Color Chart database, support printing, paint, Spinning & weaving and other industry Color Chart information
8. Cloud database support for easy data upload, sharing, and management
9. UV Illuminant, camera and Colorschemer studio for better performance
Principle
Adopt D/8 measurement structure (diffuse illumination, 8 ° direction reception), including specular reflection light and specular reflection removal mode. Light spectrum reflectance data is obtained by integrating Optical inspection device and CMOS sensor for spectroscopic measurement at 10nm intervals in the 400~ 700nm Wavelength range, and then various chroma indicators are calculated.
Applications
Printing, Paint, Spinning & weaving
Standards
CIE No.15、GB/T 3978、GB 2893、GB/T 18833、ISO7724-1、ASTM E1164、DIN5033 Teil7
Steps
1. Connect the mobile app
2. Use the camera to locate the measurement area
3. Automatic calibration instrument
4. Measurement mode and parameter selection
5. Take measurements and see results
6. Data storage or upload to the cloud
7. Use the color scheme or color correction function
Notice
• Ensure that the measurement area is clean and pollution-free
Periodic instrument calibration to ensure accuracy
• Use the appropriate measurement diameter (4mm) for small size samples
• Pay attention to the battery power, a single charge can be continuously measured 8000 times
• Avoid direct light or extreme environments
• Pay attention to information security when sharing data in the cloud
