The SY-8258 is an instrument for measuring the AC magnetic characteristics of soft magnetic materials. This instrument is ideal for new product development and product inspection carried out by the R&D, QA, and manufacturing departments of materials, core, component, and equipment manufacturers. The SY-8258 is recommended for customers who have already purchased previous models such as the SY-8232/SY-8217 and plan to purchase a second B-H analyzer. In addition to conventional B-H/Pc measurement, the new SY-8258 also integrates μ/L/Q measurement functions.
