DCP007-VIS Process Photometer

High-Precision LED Photometer for In-Line Concentration and Color Measurement.

The Kemtrak DCP007-VIS is a high-performance, fiber optic-coupled photometer designed for real-time, in-line absorbance and color measurements in the visible spectrum. Using a high-intensity LED light source, the system offers drift-free, maintenance-free operation with dual-wavelength functionality to automatically compensate for turbidity and window fouling. The VIS analyzer supports multiple color scales and concentration measurements, ideal for use in chemical, pharmaceutical, food, beverage, pulp & paper, and environmental industries.
