LIST-MAGNETIK
MP-4000
Magnetic Field Meter
with unique measuring technology for professional
measurement of magnetic direct and alternating
fields as well as pulsed fields
Experience a completely new and unique measuring technique with
the List-Magnetik MP-4000 professional magnetic field meter.
Externally connected axial and transversal field probes perform
perfect measurements of magnetic direct and alternating fields and
especially pulse fields of all kinds. The range of application extends
from the earth‘s magnetic field up to a field strength of 40,000 A/cm.
MP-4000 has a graphical LCD touch panel with an innovative operator
guidance and a resolution of 320x480 pixels. An outstanding feature
of the new probe electronics is the fast digitized measured value
processing with up to 200 kHz, which allows pulse curves from
0.1 msec to be displayed. This provides an accurate picture of the
pulse curve of a magnetic field. Maximum value and pulse length are
indicated exactly. Also alternating field curves up to 20 kHz frequency
can be displayed and stored.
The device supports all areas of application of magnetic field
measurement with flexible Data logger, combined digital and analog
display and peak value measurement. Via the Bluetooth interface,
you can transfer the data to the Windows PC as well as to the Android
or iOS app. Via the USB-C interface, the device can be connected
to an external power source in continuous operation.
Especially at very low magnetic field strengths, an absolutely inter-
ference-free and precise measurement is crucial. The measuring
electronics work directly in the probe and digitize the signals of the
Hall sensor.
In the range of stable DC fields, a magnetic field can be recorded over
a wide area with the scan function and statistically evaluated. In the
case of pulse fields, the measuring probe of the MP-4000 processes
the measurements at an enormous speed of less than 0.1 msec.
The measured values generated in this way can be displayed in the
MP-4000 as a graph and provide an accurate picture of the pulse
progression of a magnetic field.

MEASURING PROBES
for Magnetic Field Meters
MP-4000 and MP-1000
Checking with Calibration Standard
It is not necessary to calibrate the device – it is pre-
calibrated at the factory.
A calibration standard with 180 A/cm is available as an
option, in order to be able to check the device.
If a deviation is detected when checking with the
calibration standard, we advise returning the device for
recalibration at the factory.
Axial Field Probe
Place the probe inside the ring on top of the calibration
standard and position or rotate the instrument until
the maximum value is displayed. Then compare the
displayed value to the value of the calibration standard.
Transversal Field Probe
Place the probe in the center of the ring on the top of
the calibration standard with the N (North Pole) mark
facing up. Position the probe until the maximum value
is displayed. Then compare the displayed value to the
value of the calibration standard.

LIST-MAGNETIK
MP-80
Residual magnetic field meter
With the handy, battery-operated List-Magnetik MP-80 residual
magnetic field meter, you can quickly and reliably determine the
residual magnetism, also known as remanence, on ferromagnetic
iron and steel parts. The measuring device can also be used to check
demagnetized parts.
The „little brother“ of the MP-800 has its particular strength in the
area of weak magnetic fields. With its compact design and metal
housing, the device is robust and insensitive to harsh environments
such as oily vapors or moisture.
The supplied calibration standard of 5 A/cm always gives you the
certainty that your device is working correctly.
The Fluxmeter FL-4 is a measuring device for
the determination of the magnetic flux Φ (Phi)
of a magnet system or a single magnet.
In combination with the List-Magnetik Helm-
holtz moment coil HM-1, the magnetic flux
of permanent magnets can be determined
very accurately, since the entire volume
of the magnet is measured independently
of position. The effect of the magnet on the
coil is determined in the form of an electrical
voltage and converted into the flux value.

MP-1000
Magnetic Field Meter
The List-Magnetik MP-1000 magnetic field meter is a handy uni-
versal device with externally connectable transversal and axial field
probes for the precise measurement of all types of magnetic fields:
steady DC fields, alternating AC fields and pulsed fields.
A separate built-in micro controller in the MP-1000‘s measuring
probes digitizes and linearizes the analog measurement signals of the
hall sensor into the probe. This gives an extremely trouble-free and
precise measurement, especially at high magnetic field strengths.
The probe cable is pluggable at both ends, at the display unit and the
probe, which is particularly service-friendly, as the cable can simply
be replaced if it becomes faulty. Applications of the MP-1000 are the
test for residual magnetism, the measurement of magnetic fields of
all kinds, as well as the localization of stray fields for crack detection.
