The lux meter is designed for measuring the luminance of self-illuminating surfaces, such as monitor matrices, TV screens, negatoscopes, reading boards, etc. e.g. monitor matrices, TV sets, negatoscopes, reading panels, etc. lux meter guarantees an accurate measurement, regardless of the spatial distribution of the measured luminance or the backlighting of the surface to be tested. It is indispensable for checking medical screens and negatoscopes.

The unit cd/m² relates the photometric quantity cd (abbreviation for candela) to the area of the display, expressed in square metres. Another feature of the lux meter is the integrated measured value memory. With this function, measurement results can be easily saved and automatically recorded. The lux meter creates a text document in which the measured values are stored one after the other.

Due to its technical parameters, the lux meter is classified in class A according to DIN 5032-7 and TC-2.2 CIE. The measuring probe is equipped with a multifunction button that can be used to trigger a measurement, save results and set the desired measurement method, e.g. for testing the greyscale reproduction of monitors according to DICOM GSDF 1) function.
