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.
In addition, the specially designed PSA module also opens new horizons for high resolution particle sizing and allows you to measure the velocity distribution of separating particles. There is no need for you to know any material constants such as viscosity or density.
