A version of the device for exact measurement of magnetic field by the NMR method is briefly described. The device is based on the resonance absorption of r-f energy by water protons. A constant magnetic field produced by the NS magnet of an RE-1301 radiospectroscope is oriented at right angles to the r-f field. The magnetic field is stabilized by an electronic device in the 50-cps circuit. The r-f field is produced by oscillator-detector 3. The oscillatory-circuit coil is wound on a quartz vial containing distilled water and placed in airgap 2. Wavemeter 6 measures the frequency. A grid-leak-detected signal is applied to 1-f gain 500 amplifier 4. NMR signal is recorded by oscillograph 5. The field strength measuring range is 1000-4000 oe magnetic semiconductor measurements total error, 7.
