description: This work is devoted to studying the effect of magnetic field inhomogeneity on the shape of NMR signals, creating a block diagram of a small-sized NMR relaxometer, using a modulation technique for recording NMR signals in weak magnetic fields and processing NMR signals using mathematical methods, comparing the obtained signals NMR with results obtained by modeling. The maximum inhomogeneity of the field in the volume of the medium under study was determined in a smallsized NMR relaxometer. The analysis of methods for recording the NMR signal in weak magnetic fields is carried out and the choice of the modulation technique is substantiated. A block diagram of a compact NMR relaxometer is proposed. A modulation technique was applied to register NMR signals with the measurement of relaxation times. Comparison of the results obtained by modeling and experimental ones is made. The results obtained can be used in the further development of a smallsized NMR relaxometer.
