Positive Material Identification (PMI) is a fast and non-destructive testing (NDT) method for verifying the chemical composition of metals and alloys. Portable and cost-effective, PMI can be performed in one of our state-of-the-art labs, or in the field. Our Positive Material Identification (PMI) unit is a handheld LIBS (laser induced breakdown spectroscopy) analyzer, which allows users to perform rapid metal analysis.
