Advantages of PMI Testing

PMI comes with a number of advantages. It is versatile and can be used on any size or shape of component. PMI tests produce consistent results and thus have a high degree of repeatability. The XRF Analyzer used to perform PMI is a portable, lightweight device and is useful for quick analyses of components or materials. PMI is a valuable tool in any situation where the material composition of a piece of equipment is unknown or in doubt. It is also useful in situations where samples cannot be removed for routine testing. Similarly, PMI is helpful when material documentation has been misplaced or no longer available for material verification.

Smart OES portable chemical analyzer is from Hitachi PMI Master. Optical Emission Spectroscopy is the measurement of elemental wavelengths by “sparking” the material. A metallic sample is placed on the unit and the machine creates a plasma burn on the surface of the sample. The compositional elements are excited through the burn process and give off different wavelengths of light. Each separate element’s wavelength is read by the Spectro Machine and reported for alloy determination.
