ZSX Primus III NEXT Overview

Geared for industrial applications

The ZSX Primus III NEXT is an ideal tool for any industrial application, requiring elemental analysis, such as

 ∘ Minerals and Mining
 ∘ Metals
 ∘ Cement
 ∘ Ceramics and Refractories
 ∘ Glass Manufacturing
 ∘ Petrochemicals
 ∘ Chemicals
 ∘ Environment

Turnkey application packages

Industry-specific application packages are available. The "Pre-Calibration Package," which stores calibration curves at the time of shipment, the "Calibration Package," which includes standard samples and analysis conditions, and the "Master Matching Library" for standardless analysis (SQX) which is specialized for certain types of products, are available to help users start up the analysis operations.

Easy application sharing

The ZSX Primus III NEXT, ZSX Primus IV, and ZSX Primus IVi share the same hardware and software platform, making it easy to share applications between spectrometers.

Improved quality of analytical results

Have confidence in each analysis result. Measurement statistics and spectrometer physical parameters can be displayed with each analysis result to easily spot irregularities.

ZSX Primus III NEXT—your ideal partner for fast and reliable production control in highly demanding industrial environments.
