Spectral(Big Aperture/Small Aperture)

Colorimeter SP-CLR420C 421C 422C

Spectral(Two Apertures)

Colorimeter SP-CLR420C 421C 422C


It develops new color measurement method of colorimeter with build-in camera to see test area, UV light source for fluorescence color measurement; It can be connected to mobile APP and has unlimited storage memory;With built-in color card, you can find similar colors anytime, anywhere.


  • With Auto calibration
  • Different apertures: Two Apertures / Small Aperture / Big Aperture
  • Supports both SCI and SCE test which is more consistent with result of visual method.
  • Many different kinds of test parameters:Opacity, whiteness index, yellowness index and other 30 kinds of test parameters
  • Provide 26 kinds of illuminants for choice
  • Good repeatability for stable measurement (Delta E*ab 0.06)
  • Portableand massive color card database
  • Connect to mobile phone APP to create database to upload the color shades from printing, paint, textile color cards.
  • No need to carry big and heavy color card, we can find color card database from Colormeter Pro APP and find the closed/similar color easier and faster.
  • Cloud database, more convenient to view and upload
  • Official color card databases are available.Personal users can update color information to cloud and share between different instruments which make color management much easier.
  • Enterpriseusers can create and manage their own color library and formula information in the cloud and share the information to their customers and suppliers through the unique invitation code.
  • Better performance than traditional colorimeter
  • UV for fluorescence material test
  • Camera to see the test area to avoid test error
  • Paint color matching software: user can use mobile phone App to achieve color correction function.
