Real-time verification of the quality of the product: from the raw material to the final product at any stage of the production process.

Download Datasheet

The VISUM Palm is a portable NIR analyzer for real-time chemical composition determination for improved product quality, reduced production costs and lead time, and risk minimisation in the production chain.

Compact and handy. Robust and designed for industrial environments. No need for probes for background collection or qualification.

Main features

  • Raw material identification: rapid quality control of the incoming raw material in the warehouse to measure key quality parameters, adulterations detection or degradation.
  • On-site use for at-line control of key parameters for food product standardization.
  • Critical Process Parameters (CPP) monitoring along the line.
  • Non-destructive testing.
  • No sample preparation.
  • Reduction of production costs.
  • Improvement of quality and safety.
  • Higher performance.
  • Fewer customer complaints.
  • Brand image protection.
