Education NMR & MRI System

EDUMR is a desktop NMR device designed for MRI experimental teaching. Courses to teach NMR principles and experiments through MRI demonstration can be created by including EDUMR in physical corresponding majors (modern physics, applied physics, radio physics, electronic engineering, etc.) or medical corresponding majors (large-scale medical apparatus, medical imaging technology, biomedical engineering, etc.). Extensive experimental courses and majors like NMR engineering related to hardware structure can also be established with through the use of EDUMR.

Basic parameters:
1.Magnet type: permanent magnet;
2.Magnetic field intensity: 0.5±0.08T;
3.Probe coil: Ø15mm;
4.Weight: 138Kg;
