This apparatus is produced in accord with the measuring pattern of the national standard GB/T 13789-92, 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 for measuring various thickness of stalloy with cold rolling, tropism, non-tropism or hot rolling.
·The measuring result doesn't include the copper loss, guarantee its precision.
·Maintain the magnetic flux Bs sine, remove the influence of the harmonic wave.
·Add the air magnetic flux compensational coils to the test probe, guarantee the measuring result more accurate.
·According to the measuring result, draw the Ps-B loss curve manually in the coordinate paper for contrasting with the material.
