- Model PMI-Master Smart - Mobile Optical Emission Spectrometers



Seamless quality control is essential for any metalworking, especially for safety critical positive material identification on-site. But very often the spot of analysis is difficult to access e.g. plant components. The PMI-MASTER Smart is a breakthrough for optical emission spectroscopy (OES) analysis in hard to reach places. It’s the only truly portable high performance OES analyser on the market. Weighing just 15 kg / 33 lbs the spectrometer can be easily carried to the point of analysis. This robust spectrometer is designed for the precise analysis of key elements, rapid material verification, PMI and metal sorting. Despite its light weight and compact size the PMI-MASTER Smart offers high analytical performance, unparalleled portability, convenience and ease of use.

    Easy to carry, weighs only 15 kg / 33 lbs, compact dimensions.
    Ready to ship in rugged stackable cases, drag with foldable trolley.
    To comfortably and safely carry the PMI-MASTER Smart on the back.
    When needed intensively within a certain area.

    • Even in motion and temperature change with patented high resolution carbon fibre Multi-CCD optics.
    • Virtually unlimited number of channels for total spectrum analysis.
    • Concentric electrode shielding Argon flow technology for reducing air gaps.
    • Single universal adapter for measuring wires, down to 1 mm thickness.
    • Analysis of curved surfaces with unique rubber seal (e.g. pipes, rods, valves, storage tanks, turbines).
    • Windows®-based WASLab software with convenient touch screen operation.
    • Wide and customisable information display, e.g. concentrations, material name, intensity and statistical key figures.
    • Display, storage and printout of entire sample spectrum.
    • Easy to use and customisable report generator.
    • Transmission of results to remote devices & export of results into other software, e.g. Excel®.
    • Flagging results outside calibration range or material specifications.
    • Easy to use sorting function.
    • User defined access levels.
    • Optical system is fully and automatically re-adjusted.
    • Free from regulatory constraints


Simply hold the probe to the sample, push the trigger and read the result. The alloy grade and the full chemical composition appear within a few seconds on the integrated touch screen. Tailored to your specific application, different operation modes offer complete analysis, grade identification or sorting of metals. The PMI-MASTER Smart identifies the metal grade automatically and indicates where concentration limits are exceeded.


  • Low levels of carbon, phosphorus, sulphur, boron, arsenic and tin in low alloy and stainless steels.
  • L grade separation.
  • Nitrogen in duplex steels.
  • Display of analysis results.
  • Control of main spectrometer functions.
  • Extended wavelength range of probe’s optic: 165 to 210 nm.


  • Ideal for the sorting of metals with arc in air atmosphere.
  • No Argon required.
  • Analysis in only 3 seconds.
  • For tubes, wires and small parts.


  • Reliable spark analysis of standard elements, incl. C.
  • Robust construction.
  • Various sample adapters available.

The largest metals database for fast and easy grade identification is preinstalled on the PMI-MASTER Smart. It offers more than 12 million records for over 339,000 materials from 69 countries and standards. You can update your instrument’s grade database with a few clicks – no time consuming research in norms and grade catalogues.
