PolySpek Junior

The PolySpek Junior is the reliable workhorse when it comes to metals analysis. It is our entry-level model which is available as a dedicated single-base unit as well as a versatile multi-base system.

The overall optical design has been enhanced, and with improvements in CCD technology utilised to further improve the performance of the PolySpek Junior while retaining the major benefit of earlier units. This gives the PolySpek Junior the ability to analyse elements across the complete range of commercial metals and alloys. Additional bases, matrix calibrations and elements can be analysed without the additional hardware costs normally associated with classical photomultiplier spectrometers. Calibration is still required for each new material using certified reference materials


PolySpek Junior is available in different versions

Don’t worry: our product specialists will guide you to find the exact model to match your analytical needs. ARUN Technology provides analytical solutions that help improve your processes!
