VTMR TD-NMR Cross-linking Density Analyzer NMR and MRI System for
Polymer
Â
Product Description
Â
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.Â
