The rising use of nano scaled particles demands new characterization tools. Especially for polishing, grinding and lubricant-suspensions the exact knowledge of the solid concentration, the particle size and the concentration of large particles are required. The 3C-Photometer and the Large Particle Detector are especially designed for the characterization of liquid, disperse and high concentrated systems and enables to measure the size and concentration of submicron dispersions with a high resolution.





3C-Photometer - in-line Extinction-Photometer

The 3C-Photometer is a compact three color extinction photometer for applications in ultra pure and chemical aggressive liquids. The extinction measurement at three wavelengths makes this sensor particular suitable for in-line process monitoring and control of complex and high concentrated multi-phase systems, like submicron dispersions, micro-emulsions or polishing slurries. Besides extinction and color measurement the sensor can be excellently adapted for in-line measurement of concentration and particle size of submicron dispersions.

The integrated evaluation unit with a LCD-display, the RS485 interface as well as the free programmable digital or analogue output minimizes additional hardware requirements and guarantees an easy connectivity to a PC or PLC.

The 3C-Photometer replaces the Aello 1551 and 1560 series.
