Si-NIR OverLine

Rugged FT-NIR Sensor for Contactless Continuous Analysis of Materials in Motion

Si-NIR OverLine is a contactless FT-NIR spectral sensing device designed for continuous material analysis from a distance without interrupting the production flow.

It provides real-time measurements with built-in self-referencing, enabling reliable monitoring in environments where traditional sampling methods are impractical.

This configuration allows non-intrusive monitoring of materials in motion or when the sensor is mounted on moving equipment.
