LUM GmbH – Material Characterization – LUMiReader and LUMiReader PSA
The LUMiReader instantaneously measures the extinction profile of the transmitted light across the entire length of your sample. Each LUMiReader contains an optical block and temperature control element, each of which can be controlled individually. This ensures maximum flexibility and accuracy.

Brand
The LUM GmbH is one of the leading producers for analytical devices for dispersion analysis and particle characterization. On the basis of longtime experiences in the field of fluid mechanics, rheology and colloid chemistry the company, founded by Prof. Dr. D. Lerche in 1994, has developed the innovative STEP-Technology®, which is the technical platform for different product lines. Or measuring equipment is used for the fast, reliable and comprehensive characterization of any demixing phenomena in dispersions and the testing of bonding and adhesive strength of composite materials.
