4. Adopt B coil + fluxmeter to measure magnetic induction, zero shift of integrator can be self-corrected through software.
5. Adopt J coil + fluxmeter to measure magnetical polarization, remnant coil area of J coil can be automatically compensated through software.
6. Magnetic field intensity can be measured with Hall magnetometer, nonlinear error of hall probe can be corrected through software, within 0 ~ 2.4 T range, nonlinear error can be controlled within ±0.2%.
7. Adopt H coil + fluxmeter to measure magnetic field intensity, Hall magnetometer only used to indicate zero point of magnetic field so as to thoroughly eliminate nonlinear error of hall probe.
8. Optimal range of field voltage, fluxmeter and magnetometer can be automatically set up.
9. Magnetization, testing and demagnetization of general permanent magnetic sample can be completed at one time, time set up 20 seconds ~ 60 seconds.
10. Rare earth permanent magnetic samples need saturation magnetizing before testing, testing time 60 seconds ~ 120 seconds.
11. The sample after testing can be in a state of demagnetization or magnetizing, freely selected buy users.
12. Select heating head and temperature controller to detect magnetic characteristics of Ferrite, AlNiCo and rare earth material under high temperature (maximam 220°C).
13. Select shoe jig for direct measurement on magnetic shoe.
