DX-2000HC Economical Soft Magnetic Coercivity Measurement System
Soft Magnetic Materials Measurement
Automatic coercivity measurement system for soft magnetic materials using a simulated impact method with electronic integration and computer control.
Product Overview
DX-2000HC Economical Soft Magnetic Coercivity Measurement System is an automatic magnetic testing device designed for measuring the coercivity (Hc) of soft magnetic materials.
The system adopts the simulated impact method combined with computer control technology, A/D and D/A conversion, and electronic integration. It replaces the traditional impact galvanometer used in classical measurement systems.
