td81 series testing system for ac magnetic of soft materials

the td81 series automatically measures the ac magnetic properties of soft magnetic ring specimens in the frequency range of 20 hz to 1 mhz / 3 mhz (customized) and draws the relevant magnetic curves.


td81 series meets national standards gb/t 3658-2008, gb/t 19346.1-2017,and international standard iec 60404-6.


- measuring materials : soft ferrite, electrical pure iron, silicon steel, nife (permalloy), cofe alloy, amorphous and nanocrystalline alloys, metal magnetic powder core, etc.

- sample shape: ring-shape, u-shape, e-shape.

- measurable parameters : bm, hm, jm, ps, μa, δ.


- standard samples are only used for comparison of measurement data and cannot be used to calibrate the unit.

- reliable accuracy and repeatability in the 20 hz to 1 mhz / 3 mhz (customized) range.

- equipped with pc software, only manually place samples and set parameters, other processes are automatically completed.
