 The Mag-01 and the Mag-01H are portable high
performance instruments that provide precision measurements
of the direction and intensity of magnetic fields from
0.1nT (1µG) to 2,000µT (20G) with a frequency
response of DC to 10Hz. Axial and transverse probes
are available together with unpackaged probes for cryogenic
applications.
Both the Mag-01 and the Mag-01H instruments may be powered
by either mains voltage or internal battery, and have
a 4½ digit display and an analog output. The internal
rechargeable sealed lead acid battery provides up to
16 hours continuous use and may be recharged using the
mains adaptor provided.
The Mag-01 provides a maximum resolution of 1nT while
the Mag-01H has an additional x10 sensitivity switch
for a resolution of 0.1nT and an offset control for
up to ±90µT in 10µT steps.
These instruments feature superb linearity, accuracy,
and very low drift with time and temperature. Calibration
is traceable to international standards, and a re-calibration
service is available.
Probes for the Mag-01 and Mag-01H
The
sensing axis of the Mag-B and Mag-D probes
is along the axis of the cylindrical enlosure (axial)
and the sensing axis of the Mag-C and Mag-E
probes is along the axis of the short cylinder mounted
at the end of the probe (transverse). The magnetic detection
axis and center of sensitive volume are marked on each
probe.
The
cryogenic Mag-F and Mag-G probes are suitable
for operation at temperatures down to liquid helium
and have 1 meter of 4 x .02mm enameled copper wire connected
to the sensing element for use in a cryostat or vacuum
chamber. This length can be extended to a maximum of
5 meters if required.
