The PCE-LMD 100 lux meter is specifically created for measuring the brightness of self-illuminating surfaces like monitor displays, television screens, negatoscopes, and reading boards. This device ensures precise measurements, regardless of the pattern of light across the surface or its backlighting. It is essential for verifying the luminance of medical screens and negatoscopes.
The unit cd/m2 relates the photometric quantity cd (abbreviation for candela) to the display area, in square meters. Another feature of the lux meter is the built-in memory of measured values. With this function, measurement results can be saved easily and automatically. The light meter creates a text document in which the measured values are stored one after another.
