3C-Photometer – in-line Extinction-Photometer
The 3C-Photometer is a compact three-color extinction photometer for applications in ultrapure 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.
Applications
- High dynamic extinction measurement
