Vertical PhotoMeter

The vertical photometer measures color data through the reflection or transmission of light from samples, using a 45° annular illumination and 0° detection geometry. It is used for surface color difference control in coatings, plastics, and other materials, and is calibrated with a standard white board to directly read L*a*b* values.
Selection
When selecting, consider matching the measurement aperture to the sample size, ensuring repeatability error is less than 0.08 ΔE, and compatibility with existing color management systems. Check whether the instrument table height suits operational habits and verify the validity of the calibration certificate issued by the national metrology institution.
