Digital Luminance Meter

A digital luminance meter receives reflected light from an object's surface through a photoelectric sensor, converts it into an electrical signal, processes it, and displays the luminance value. It is used to measure the surface brightness of materials such as paper, plastics, and coatings, and is employed in the printing and papermaking industries to control product quality.
Selection
When selecting, ensure the measurement range covers the sample's luminance interval, with repeatability error lower than industry standards. The observation aperture should match the measured area, and the calibration certificate must be valid. The instrument probe structure should suit the detection environment, and the data interface must meet recording requirements.
