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.

NMR Probes
CAYLAR has developed several probes to meet the maximum needs:
​
​
Standard Probes:
-
Optimized for the best signal-to-noise ratio with a high dynamic range.
-
Low sensitivity to gradient (typically between 1000 and 2000 ppm/cm).
-
Miniaturized Probes
​
Probes for Radioactive Environments:
-
No electronic components within 11cm of the NMR sample.
-
For highly radioactive environments, no electronic components within 40cm of the NMR sample.
​
Specific Probes Made on Request:
-
Gradient sensitivity.
-
Probe size and shape.
