Paper Luminance Measuring Instrument

The paper brightness meter quantifies the whiteness of paper by irradiating the paper sample with specific-wavelength blue light and detecting its reflectivity. It is used for process control in papermaking and inspection of finished products, reflecting the visual whiteness of the paper.
Selection
When selecting, ensure that the measurement geometry meets industry standards, with a wavelength of 457nm. Consider the sample placement method to align with the production process, and the instrument must be regularly calibrated using a standard white board.
