Magnetic inspection often calls for the use of a specified level of magnetic flux within steel components. If the magnetic flux level is too low, then defects may be overlooked: if too high then spurious indications may occur. The MF300B has been produced to measure the magnetic flux density just below the surface.

The magnetic flux is measured simply by placing the probe on the surface of interest. The monitor will measure constant or alternating magnetic flux which can be produced by permanent magnets, electromagnets or electric currents. The measured value is displayed in units of Tesla.

Measurements of magnetic flux are displayed on the unit and can also be sent via an RS232 link to a P.C.

Software for use with the meter is provided which enables data to be saved and entered in spreadsheets.
