NMR20 TESLAMETER
Nuclear Magnetic Resonance Teslameter
CAYLAR offers a magnetic field measurement by Nuclear Magnetic Resonance (NMR) which allows an absolute measurement of the magnetic field, with a resolution of 10 nT (0.1 G) without temperature influence. NMR probes associated with the NMR20 have the particularity of having a large measurement range with a dynamic range of 5 and measure low fields from 140 G (14 mT) up to 13 T
NMR20 Precision Teslameter
(NMR Gaussmeter)
The NMR20 Teslameter measures magnetic fields using the principle of nuclear magnetic resonance (NMR).
This is the most precise technology for measuring an absolute magnetic field value.
