The Diverse Ferrite meter MF300F+ measures the Ferrite number (FN) of austenitic and duplex stainless steel weld material. It has a probe that is sensitive to ferrite content in a 10 mm area to a depth of approximately 1 mm.
This results in sensitivity to a small well defined volume and excellent response over the full range of ferrite samples. An air-cooled version of the probe allows Ferrite measurement of hot samples.
Storage of up to 52 measurements is included on the standard instrument. Communication with a PC, via RS232 or USB, is provided as an option including downloading of the measurement log.

Salient Features of MF300F+
