This apparatus is produced in accord with the measuring pattern of the national standard GB/T13789-92, combined the chip machine control technical with A/D and D/A, sine wave excitation power inside, display the iron loss Ps (W/kg) directly.

• suitable of measuring various thickness of stalloy which with cold rolling tropism non-tropism or hot rolling tropism.
• the measuring result doesn't include the copper loss, guarantee its precision.
• maintain the magnetic flux Bs is sine, remove the influence of the harmonic wave.
• add air magnetic flux in the measuring probe to compensate the coils, guarantee the measuring result is more accurate.
• according to the measuring result, draw the Ps-B loss curve in the coordinate paper by hand, for contrasting with the material.
