AS-active-probes – Overview Earth Magnetic Field
For the measurement of very small fields like e.g. the earth magnetic field
we offer our probes of class Ultralow. With the possibility of compensation of
±70 µT the overlaying earth magnetic field can be masked. So even very
small stray and noise fields can be measured with this probes.

AS-active-probes – Overview High Field
Especially for the measurement of very high field the probe AS-HAP of class
High has been developed. Such high permanent fields are normally only
achieved with superconductors. Temporary they can be generated with
other setups, too.
