Luminescence meter - Ziegler LUMI 12


Luminescence meter with analogue display

The ZIEGLER LUMI 12 measuring device is a compact tabletop device with a UV light sensor that outputs the luminescence (wavelength 450 - 750nm) of the test material. The luminescence value is measured by the sensor and displayed on the analog display on the device. The measuring range of the luminescence value is 5-12 LAETUS corresponding to CIBA GEIGY degree of whiteness. It is suitable for directly reading the luminescence value of paper, plastic materials, coatings, etc.
