GAOTek Reception Colorimeter

GAOTek Reception Colorimeter utilizes a 45/0 geometric optical structure (45-degree ring illumination, 0-degree reception) following CIE No. 15 standards.




GAOTek Reception Colorimeter utilizes a 45/0 geometric optical structure (45-degree ring illumination, 0-degree reception) following CIE No. 15 standards. It employs concave grating spectrometry for precise measurement of sample reflectance and colorimetric data. The instrument features a large Φ20 mm measuring aperture suitable for traffic signs, color matching, and precise color transfer.



  • Beautiful, ergonomic design with geometric optical structure
  • High-life, low-power LED light source (including UV/excluding UV)
  • Φ0.7874 ap INerture for larger, uneven samples
  • Measures spectra, provides accurate Lab data
  • High-end hardware: TFT screen, capacitive touch, concave grating, CMOS detector
  • Dual USB/Bluetooth 4.0 communication compatibility
  • Stain-resistant white calibration plate, extensive data storage
  • Dual observers, multiple light sources, color systems
  • Feature-rich PC software, function extensions
  • Built-in tolerance settings, specific traffic sign gamut
