What is PMI (Positive Material Identification)?
PMI verifies that the metal you installed is the metal you specified.
PMI (Positive Material Identification) is the practice of verifying alloy grade and composition on components, welds, and incoming materials.
Industries with safety-critical assets — oil & gas, power, aerospace, pharma — rely on PMI to prevent wrong-grade failures.
Portable XRF is the most common PMI tool because it is fast, non-destructive, and field-ready. Specelex Grade ID returns results in about one second.
