The new magnetic system construction and the registration circuit of the nuclear magnetic resonance signal in the weak magnetic field are considered. The peculiarities of nuclear magnetic resonance signal registration with the application of modulation method in the weak field from the small volume of liquid medium (less than 0.3 ml) are determined. Taking into account these peculiarities in the new elaborated construction of the small nuclear magnetic spectrometer gives a possibility to register signals from different nuclei of investigated medium, having magnetic moment. That expands greatly the functional possibilities of the nuclear magnetic resonance in the investigation of media in the express-mode. The experiment investigation results for different media are represented.
