Photoelectric Integrating Sphere ColoriMeter

Photoelectric integrating colorimeters simulate the human eye's response to red, green, and blue light through built-in filters, measuring the integrated value of reflected light from objects to calculate color differences. They are used in industries such as coatings and plastics for on-site rapid color comparison and quality control, offering ease of operation but limited accuracy.
Selection
When selecting a photoelectric integrating color difference meter, consider matching the measurement aperture to the sample size, and choose between fixed or variable aperture models. Pay attention to the instrument's repeatability and long-term stability, and ensure that the accompanying software meets the basic requirements for color difference analysis. Select a flat or pointed measurement probe based on the surface shape of the commonly measured objects.
