Introduction to the Gaussmeter
Discover the precision of magnetic field measurement with CAYLAR’s NMR technology, providing absolute measurements unaffected by temperature variations.
For several decades, Nuclear Magnetic Resonance has been recognised as the ultimate reference method for magnetic field measurement, and CAYLAR continues to advance in this field.
The NMR20 Gaussmeter, successor to the NMR 2 (Teslameter NMR DRUSCH), is based on a technology proven since the 1970s, now optimised to meet today’s requirements.
The NMR20 features an FPGA-based frequency meter and an embedded system, delivering measurements that are more stable, faster, and more accurate than those of a conventional NMR teslameter.
With fast NMR signal detection, high gradient tolerance, an extended measurement range, increased resistance to radiation, and enhanced reliability, the NMR20 is a reference solution for precise magnetic field measurement.
Applications
- MRI (manufacturers, installers, maintenance)
- Accelerators & Synchrotrons
- Metrology & Calibration
- Precision physics experiments
