Visum NIR In-Line™ - in line NIR analyzer

Real-time and in line NIR analyzer: accurate and continuous measurements for process optimisation and quality control in the plant.


Visum NIR In-Line™ is a versatile and accurate NIR analyzer for real-time chemical composition analysis in production lines. It adapts to different geometries and types of installations (conveyor belt, pipeline, tank, etc.). It can also be integrated into process machinery (e.g. blenders).

Unlike other in line NIR analyzers, the installation of the Visum NIR In-Line™ does not involve major modifications to the line, is minimally invasive and offers reliable and accurate results to have the product under control at all times, providing information to the plant systems to detect and correct any anomalies and to meet the highest quality standards. In addition, we perform ad-hoc calibrations, leaving behind generic libraries that do not fit the requirements of the product, its nature and origin.

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
