Magnetic field modulation method! A high-performance magnetic field measuring instrument that achieves compactness, lightweight design, and cost reduction.
The "EFM-100M" is a magnetic field measuring device that detects NMR signals and enables high-precision measurements. It is a standard measurement method for measuring absolute magnetic fields, compared to measuring devices using Hall elements. Additionally, by adding a probe, it can measure magnetic fields in the range of 0.1 to 1.8T. 【Features】 ■ Utilizes NMR (Nuclear Magnetic Resonance) ■ Easy measurement with automatic search function ■ Direct reading of frequency and magnetic field strength values ■ Measurement data can be read out *For more details, please download the PDF or feel free to contact us.
