Visum in-line

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

Download Datasheet

The VISUM InLine 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 InLine is a robust inspection system designed for harsh industrial environments

Main features

  • Continuous monitoring of Critical Quality Attributes (CQAs) ensuring measurement of all the product units.
  • Real-time and simultaneous measurement of Critical Control Parameters (CCPs) for keeping the production process under control.
  • Fraud detection
  • Unexpected Anomaly Detection: Early warning in the event of unexpected changes in the product’s composition
  • Non-destructive testing.
  • No sample preparation.
  • Product standardization.
  • Reduction of production costs
  • Improvement of quality and safety.
  • Higher performance.
  • Fewer customer complaints.
  • Brand image protection.
