TH8010 Electrical Steel Magnetic Measurement Device Calibration System
1. Summary
TH8010 is an instrument specially used for traceability calibration of electrical steel magnetic measuring devices. Its absolute measurement uncertainty is at least 3 times higher than the accuracy of the current mainstream commercial magnetic measuring instruments in the world (excluding errors caused by SST and EPS).). The magnetic parameters can be traced back to basic electromagnetic physical quantities, and the performance of the electrical steel magnetic detector can be comprehensively analyzed.
