 Unique Equipment for Ferrite Cores Testing.
The only mechano-tronic ferritecores tester on global market.

AL-METER i unique (semi automatic) equipment to measure AL parameters of the ferrite cores by measuring an inductance of reference coil positioned in the middle of the core. Air gap error is supressed by mechanical system (Twisting device) pressing the cores together.

Twisting device
Twisting device is a mechanical system digitally controled pressing the ferrite cores closely together to avoid an air gap error.
