Grating ColoriMeter

The grating colorimeter disperses light into a spectrum using a diffraction grating. Sensors measure the reflectance data at each wavelength, and the instrument calculates the color values of the object. It is used for color difference detection in paints and inks, color quality control of plastic products, and color consistency verification of printed materials.
Selection
When selecting, consider matching the measurement aperture to the sample size, ensuring the observation light source type complies with industry standards, guaranteeing inter-instrument consistency for data accuracy, choosing a measurement mode suitable for flat or curved samples, selecting data interfaces that meet transmission requirements, and ensuring the environmental temperature and humidity are suitable for working conditions.
