The ZIEGLER LUMI 12 measuring device is a compact tabletop device with a UV light sensor that outputs the luminescence (wavelength 450–750 nm) 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.
Luminescence measuring rods
The LUMI 12 measuring device is calibrated at the factory. A LAETUS measuring rod is used for this purpose. The included ZIEGLER functional test strip can only be used for simple testing of the measuring device’s functionality.
