Metrolab Three-Axis Teslameter (Gaussmeter), THM1176, 

The Metrolab THM1176 and TFM1186 are unique three-axis Magnetic Field Probes with USB Interface and power via the interface.

Fields from nT to 20 T, DC to 1kHz, can be measured with 1% accuracy. All three axes of the magnetic field are simultaneously measured to give an accurate total field amplitude independent of Probe orientation. The entire instrument has been reduced to a cable that can plug directly into the USB port on your PC or battery-powered handheld computer.

The THM1176 and TFM1186 are available in two configurations:
Three-axis Magnetic Field Probe with USB Interface:
Utilizes a USB connector to connect to the Hall or Fluxgate probe to a computer with the supplied software that displays the total field and the components, numerically or graphically, records and plays back measurements, and allows you to scan a volume to find the maximum field value.
PC Software is compatability with Windows 7, Vista, XP, Server 2008 and Mac OS X.

Three-axis Magnetic Field Probe with USB Interface and Tablet:
Industrial quality handheld computer allows you to take the Teslameter (Gaussmeter) anywhere you need. A heavy-duty battery, plus a spare, provides an autonomy of nearly a full working day. The AC adaptor comes with plugs for Europe, UK, USA and Australia. The software has the same functionality as on the desktop computer; source code is included. It all comes in a convenient, padded carrying case..

Common applications include: Testing of medical devices and monitors for MRI compatibility. Safety control in an MRI environment e.g. 5 Gauss line mapping, permanent magnet QC, mapping of magnet fringing field contours, evaluating magnetic shielding effectivenes, magnetic remanence mapping, magnetic particle inspection waveforms, compliance with IATA regulations for magnet shipments.
