Mixed material, stamping of the wrong grade, lost the paperwork or having the wrong paperwork are all scenarios that have happened and continue to happen in the metals industry. These are the circumstances that make it necessary for PMI to be performed at multiple stages of delivery and processing.

A Handheld XRF PMI gun can analyse, identify and display grade and composition of a material in seconds without creating any marks on the material or destroying the sample in any way.
For optimal efficiency and safety, a PMI program ensures that every part installed meets the specification required to stand up to the demands of the working environment.
