Process NIR & FT-NIR analyzer for real-time monitoring

Visum NIR In-Line™ is an industrial NIR / FT-NIR analyzer designed to continuously measure moisture, fat, protein, and other composition parameters in real time, directly on the production line. This NIR analyzer enables continuous monitoring of mixing and drying processes, as well as other critical quality parameters, helping manufacturers detect deviations and optimize production without interrupting the process.

Thanks to its versatility and different integration configurations, Visum NIR In-Line™ can be adapted to a wide range of products, processes, and applications across industries such as food and beverages, animal feed and nutrition, pharmaceuticals, chemicals, and polymers, including processes subject to GMP requirements.

Turnkey In-line Process Integration

Visum NIR In-Line™ is a fully autonomous industrial NIR analyzer that integrates the sensor, computer, and software into a single compact and robust device. Available in NIR and FT-NIR configurations, it is designed for direct installation on existing production lines and processing equipment, minimizing process modifications and enabling fast commissioning and reliable continuous operation.

This inline NIR analyzer adapts to different process configurations, including mixers, conveyor belts, screw conveyors, pipes, reactors, tanks, and dryers, through different measurement geometries and integration options. It also supports communication with PLCs and industrial control systems, allowing analytical results to be directly integrated into process monitoring and automation.

Thanks to its flexible architecture, Visum NIR In-Line™ can be integrated into both conventional industrial installations and pharmaceutical environments subject to GMP requirements, providing a solution tailored to the technical and operational needs of each application.
