MicroMR

-----------------------------------------------

The MicroMR is a NMR imaging and analyzing instrument, with independent pulse sequence generator, RF transmitting and receiving coils, to enhance the signal-to –noise ratio of the NMR signal. The MicroMR includes temperature control for higher accuracy and precision. The operator can modify the pulse parameters for each application. This instrument performs spectrum analysis, and provides two and three dimension images. System is ideal for researching fluid distribution, permeability distribution, multi-phase flow, saturated and unsaturated seepage of materials.
