Handheld Luminance Meter

A handheld brightness meter receives reflected light from an surface of an object through a photoelectric sensor, converts it into an electrical signal, and calculates the brightness value. It is used to measure the surface brightness of materials such as paper and plastic, providing direct numerical readings for applications like print quality inspection and uniformity testing of coatings.
Selection
When selecting, consider that the measurement range covers the sample brightness interval, the probe size matches the measured area, and the calibration certificate ensures accurate values. The ambient light compensation function reduces interference, the portable design adapts to on-site testing, and the data interface meets recording needs.
