Why is the three angles color spectrophotoemter suitable for automobile paint color matching?

As for the color matching scheme of automobile paint, there are various colors in automobile paint. In order to improve the color matching speed, “triangle color difference meter + computer color matching system” has several characteristics compared with manual color matching:

  • 1. It makes color matching job much easier.
  • 2. It can gives different options.
  • 3. Fast test twice can get formula.
  • 4. Simple instrument interface which is easier to use.
  • 5. Rubber pat to prevent the instrument from sliding when reading
  • 6. Small aperture which is convenient to measure on curve surface
  • 7. Bluetooth function can be custom made to connect with mobile devices.
  • 8. Three angles to get the test result from different test angles.
  • 9. Light weight, small size and easily carrying
  • 10. Instrument adopts LED light which is long lifetime, can be used for 10 years.
