Visum NIR In-Line

Real-Time Product Monitoring: In-Line and continuous measurements to improve process quality inspection


The Visum NIR In-Line is a Industrial NIR analyzer for real-time and continuous chemical composition monitoring adapted to several types of geometries and unit operations (conveyor belts, pipes, tubes, etc.) and unit process machinery (e.g. blenders).

Visum NIR In-Line is a robust inspection system designed for harsh industrial environments
