CAYLAR NMR  Gaussmeter and Probes

         Group3 is proud to announce its collaboration with Caylar, a French scientific instrumentation company specializing in the design and manufacture of magnetic systems (electromagnets, power supplies, gaussmeters) combining the historical know-how of DRUSCH and BOUHNIK.


         CAYLAR is one of the few industrial players to offer complete magnetic systems for producing, measuring and regulating a magnetic field with high precision and stability.

NMR Gaussmeter

CAYLAR proposes a measurement of the magnetic field by Nuclear Magnetic Resonance (NMR) which allows to have an absolute measurement of the magnetic field without influence of temperature.


The Gaussmeter NMR20 is the successor of the famous Gaussmeter NMR 2 (Teslameter NMR DRUSCH). An approved technology since the 70's.


The new 2022 version of the NMR20 offers unmatched performance in all aspects. With the new FPGA-based frequency meter, the field reading is improved, more stable, more accurate with a hundred times higher resolution.
With the new embedded system, the NMR20 is faster, turns on instantly, more reliable and secure.
