PR0120 - Opacity and Color Analyzer

PR0120 - Opacity and Color Analyzer

Measurement system for color and/or opacity in production and the lab.

The Opacity und Color Analyzer lets you test color and opacity of products reliably and with long-term stability. The system is divided into a powerful measurement electronics section (PR0120) and a highly stable light source (PR0108). The measuring range for opacity using transmitted light is from 0 to 5 (OD0 to OD5). Using reflection the system uses the CIELab color space with a long-term stability of the dE of <0.2. The measuring circuitry works in conjunction with the intelligent light source with a sampling rate of 2 KHz. Availability of different optics permits high variability in the application.
