Ferrite Content Measurement of Stainless Steels

The rugged FERRITSCOPE FMP30 handheld measurement gauge with plug-in type smart probe is suited to the fast, non-destructive and accurate measurement of ferrite content in stainless steels on-site or in the lab according to the magnetic inductive method. The Ferritescope FMP30 ferrite content measurement gauge operates by generating an alternating magnetic field in the sample which is proportional to the ferrite content and which the instrument can detect. The Ferritescope measures the relative permeability of a material in the alternating magnetic field of its probe. This provides a ferrite content reading, which is largely uninfluenced by various extrinsic parameters (lift-off, strain in specimen, curvature of specimen surface, thickness of welded material). The results of comparison measurements have confirmed that the values obtained are correct and these ferrite gauges are widely specified as essential on projects ranging from oil exploration, chemical production, utility and other processing plants exposed to heat, aggressive media and high pressure.
