Stefan-Mayer FAST MR-3 three-axis magnetic field canceling system for electron microscopes (SEMs and TEMs), electron/ion beam and laser experiments, nanotechnology, bio-magnetic investigations, etc. High reliability thorough rugged analog design. No tedious programming, no crashes, no digital-to-analog noise pulses in the cancellation coils that could compromise optimal imaging performance for EMI sensitive ion-beam and laser research tools.
The magnetic field at the tool column is measured with a low-noise 3-axis fluxgate sensor. The controller unit contains the sensor, control electronics and low impedance current pumps for direct connections to the dual orthogonal Bx, By and Bz compensation coils. Quasi-static DC magnetic field changes caused by trams, subway, trucks, and elevators are effectively reduced as well as AC magnetic fields from power lines and other higher frequency EMI sources.
The magnetic field compensation system MK-1 has been designed for single axis compensation of magnetic field disturbances such as MRIs. The system reduces slow disturbances caused by trams, elevators, vehicle, and even magnetic noise produced by power lines by establishing a compensation field with the help of suitable compensation coils. The system is suitable for applications where the magnetic field sensors must be places outside the compensation coils so that feedback operation is not possible.
Vitatech is an authorized distributor and installer of Stefan Mayer Active Compensation Systems. We offer wall mounted or free-standing Helmholtz coil units with industry leading regions of magnetic homogeneity. Our team designs and installs the appropriate cancellation coil system with maximum attenuation depending on the ambient conditions of the site. Cancellation coils can be mounted to the walls or integrated into a self-supporting aluminum / non-magnetic frame. Vitatech offers turn-key installation services. Call us today for a quote.

The magnetic field sensor FLC 100 is a miniature fluxgate magnetometer with high resolution for the measurement of weak magnetic fields up to 100 μT. This sensor can be used in any application where the sensitivity and stability of conventional magnetic field sensors (Hall or MR sensors) is too low, e.g. for the measurement of the earth’s magnetic field (for navigation) or if ferrous object should be detected at larger distances.
Low noise integrated circuit magnetometer ready to meet your product development needs.
High-sensitivity miniature triaxial fluxgate magnetometer for the measurement of weak magnetic fields up to 200μT. This sensor can be used in any application where the sensitivity and stability of conventional magnetic field sensors (Hall or MR sensors) is too low, e.g. for the measurement of the earth’s magnetic field (for navigation), where simultaneous three-axis measurements are needed.
The teslameter FLUXMASTER is a very compact hand-held instrument which has been
designed for accurate measurements of weak magnetic fields from 0.1 nT (nanotesla) to
200 μT. The instrument operates on the fluxgate principle. It consists of a cylindrical
sensor which is connected with the electronics unit via a 1.5 m cable. The magnetometer
is optimized for low offset, low noise and high stability. The magnitude of the measured magnetic field component can be read in μT from from a 4 1/2 digit LC-display. Three
full scale ranges are available.
The FERROMASTER is a compact hand-held instrument made for easy measurements
of the relative magnetic permeability μr of materials and workpieces with μr between
1.001 and 1.999. The relative permeability is measured by touching the workpiece
with the sensor tip and reading the result from the LC display. Automatic zeroing is
performed by simply pressing a button.
