Hemispherical geometric structure coloriMeter

The hemispherical geometry colorimeter utilizes the principle of integral sphere diffuse reflection, employing a built-in light source to uniformly illuminate the sample surface and measuring the reflected spectral data to calculate color difference values. It is used for surface color quality control of materials such as coatings and plastics, capable of eliminating texture interference, and is suitable for color difference detection of materials ranging from matte to high-gloss finishes.
Selection
When selecting, consider matching the measurement aperture to the sample size and confirm that the instrument complies with industry standards. Check the durability of the integrating sphere material and evaluate whether the software functionality meets daily analysis needs. Compare the measurement stability of different models to ensure adaptability to the temperature and humidity conditions of the production environment.
