Handheld NIR analyzer

Visum Palm™ - Handheld NIR analyzer

Handheld NIR analyzer for use in the field or at different points in the manufacturing process, from raw material to final quality control.


The VISUM Palm™ is a handheld NIR analyzer, easy-to-use for real-time chemical composition determination of a wide variety of materials and mixtures, thus reducing laboratory analysis times, production costs, lead time and minimizing risks in the production chain.

In addition to a powerful spectrophotometer, the Visum Palm™ analyzer has a 10 mm measuring spot and an illumination and light collection system that together guarantee to take advantage of the maximum information available in the scattered light due to the heterogeneities present in real-world samples. It has an autonomy of 5 hours of intensive use, full Wi-Fi connectivity and does not require sample preparation, specialized personnel or specific probes. Among its most popular applications are the verification and control of raw materials, anomaly detection, food analysis, quantitative and qualitative determinations of APIs and excipients as well as the identification of polymers, classification of plastics, among other materials and products.
