PMI / Positive Material Identification

Handheld XRF PMI Gun for Alloy Verification

Q: Is a handheld XRF PMI gun accurate?

A handheld XRF analyzer identifies elements via their characteristic X-ray fingerprint. Combined with an alloy grade library it delivers non-destructive grade identification in seconds, accurately measuring Cr, Ni, Mo and other key alloying elements to meet on-site PMI and material reliability requirements in petrochemical, power and pressure vessel industries.

Q: Does PMI testing damage or cut the sample?

No. Handheld XRF is fully non-destructive, requiring no cutting, grinding or sampling. You can spot-test directly on pipes, valves, welds and components, making it ideal for in-service equipment and finished goods.

Q: How long does a single PMI test take?

Routine alloy grade identification typically returns results in 1–3 seconds; for more precise trace and light-element analysis the measurement time can be extended to tens of seconds.

Built for petrochemical, power, pressure vessel and manufacturing industries, the Scensor handheld XRF delivers fast, non-destructive positive material identification (PMI) and material reliability verification — confirming alloy grade and key element content right on site.
