Light Meter

The light illuminance meter converts light energy into an electrical signal through photosensitive elements to measure the luminous flux received per unit area. It is used to evaluate the brightness of lighting environments, control exposure times in the printing industry, detect paper whiteness in laboratory settings, and monitor light intensity during plastic aging tests.
Selection
Select models with matching spectral responses based on the type of light source being measured. Ensure the measurement range covers the actual illuminance levels and confirm that the accuracy meets standard requirements. Consider matching the sensor size to the measurement scenario, opt for waterproof designs for outdoor use, and ensure calibration certificates guarantee data reliability.
