More Fluxgate MagnetometerAn instrument to measure magnetic flux density (B) or magnetic field intensity (H). More TFM1186 is a member of Metrolab’s THM1176 family of 3-axis handheld magnetometers. It is a lightweight, low-power, go-anywhere fluxgate magnetometer. Outstanding noise characteristics make fluxgate magnetometers the instrument of choice for measuring minute disturbances in the local magnetic field, for example due to an iron mass or AC power-line noise. The TFM1186 has a rangeThe range of a probe is defined by the minimum and maximum field strength it can measure. On an instrument,...

The entire instrument has been reduced to a cable with a few fat spots, which can plug directly into your PC or into a battery-powered handheld computer.

Desktop, Handheld and Duo Kits

If you just want to plug a magnetometerAn instrument to measure magnetic flux density (B) or magnetic field intensity (H). More into the USB port of your computer, you need the Desktop Kit. The Handheld Kit, with its optional battery-operated, industrial quality tablet computer, takes the measurement from the lab bench to the field – although of course you can still use the instrument with your computer, too. If you also need to measure higher fields, the Duo Kit provides a practical and cost-effective package of any two probes in the THM1176 family, with or without handheld computer.

All kits include a USB stick with the manual, software for Windows and Mac, and all source code. The handheld kits include a carrying case with the tablet, charger, adapters and cables.

The computer interface complies with the USB, USBTMC/USB488, DFU, SCPI and VISA standards, and is compatible with Windows, Macintosh and Linux based computers.

Software that works

The supplied software displays the total field and its x, y, z components, while a “3D Compass“ permits direct visualization of the vector direction. FFT, RMS or Peak-to-Peak computations can also be displayed, both numerically and graphically.

More rate, trigger mode and data averaging. Visual and auditory alarms can be used to signal when measurements are out of bounds. Last but not least, measurements can be recorded to a file, played back in any of the available display modes, or transferred for further analysis using, for example, Excel or Matlab.

More minimizes the effect of temperature fluctuations. Different trigger modes are designed to support signal averaging, AC measurements, or synchronization with external events. Results can be displayed in T, mT, µT, nT, G or mG. The firmware can be upgraded by the user. Even the signal cable between the sensor and the electronics is specially designed to minimize induction effects.
