PDA-based magnetometer
A new magnetometer was presented by Narda Safety Test Solutions at Arbeitsschutz aktuell 2008. The THM1176-PDA device, which consists of a high-performance PDA and a precision, non-directional probe connected via USB, can be used as a stand-alone hand-held unit or in conjunction with a PC. It measures magnetic fields having flux densities of up to 20 Tesla in the frequency range from 0 Hz to 1 kHz.
The THM1176-PDA can be used anywhere where high magnetic field strengths need to be measured and monitored: on scientific and medical equipment, such as magnetic resonance tomographs; in industry on equipment for smelting metals, or on transformer stations and large-scale electric motor drives, such as railroad locomotives.
The technical advantages of the new magnetometer are:
• Non-directional measurement thanks to isotropic, 3-axis Hall-effect probe, so the result is independent of the probe direction relative to the field
• very small sensor area gives pinpoint accuracy when measuring strong, non-homogeneous fields
• Simple operation using the PDA touch screen or MS-Windows PC software (everything is included in the package)
THM1176-PDA is a product of the Swiss company METROLAB Instruments SA, the leading supplier of precision Tesla-meters for high magnetic field strengths. It extends the program of test equipment for magnetic fields offered by Narda Safety Test Solutions to cover the low frequency range right down to DC fields.

FGM single axis fluxgate magnetometers are rugged, accurate, highly sensitive portable hand held instruments for measuring DC magnetic fields from 1 gamma (1 nTesla) to 2 Gauss.
These small and highly stable portable instruments, powered by a conventional 9 volt alkaline battery, can measure DC magnetic fields to an absolute accuracy of ±0.5% traceable to NIST, with linearity better than ±0.02% on all ranges.
All FGM instruments have three ranges: ±20 mGauss, ±200 mGauss, and ±2000 mGauss. The 3½ digit LCD display (or optional 4½ digit display) provides a resolution of 0.05% (1 gamma on the 20 mGauss range).
There are no zero or gain adjustments required. The fluxgate magnetometer design inherently results in very stable and accurate performance.
A buffered analog output is provided which can be used to drive a strip chart recorder or connect to a data acquisition system. The wide frequency response of DC to 100 Hz (optional DC to 400 Hz) of the analog output allows the user to monitor fast moving magnetic signals and measure 50/60 Hz powerline fields.

The characteristics of STL's Digital Magnetometers are very low noise, large dynamic range and high linearity. STL's Digital Magnetometer Series are combining STL's unique 26- Bit high resolution low noise data acquisition system, state of the art low noise fluxgate sensors and STL's data acquisition software. The digitalisation is located close to the Fluxgate sensor. These provide complete and miniaturized three- axis high end magnetic field measurement systems using any notebook having a PCMCIA Type II PC card slot. For complex multi channel measurement systems an Ethernet connectivity is available. The DM series covers a range from 80 uT to 1 mT. The max . Bandwidth is 4 KHz.
Digital temperature compensation minimizes drifts.
Sensor output is digitally error- corrected with respect to scaling, offset and alignment. A single coax cable power and data communication introduces minimal magnetic signature. The small size and lightweight system is ready to use.
++++ STL is looking wordwide for Dealers for the DM Series +++

With the INPHYNIX probe M magnetometer, new hands-on sessions based on magnetic induction are open.
Previous difficult and sensitive phenomena, linked to magnetic field, can be now accurately measured. As simple example : the characterization of B circulation around electrical line charged with only 100mA.
The probe M is more sensitive ( ten times more) than previous oldest Hall probe.
This dual axis sensor has very large bandwidth and is perfectly adapted to be daily used by students.
With additional INPHYNIX tools, like ISOFLUX or ABS (Ampère, Biot & Savart), you got in hands turn key solution with all educational equipments to create or improve more practice sessions with better sensitivity and accurate measurements. These sessions will perfectly follow up and supplement the theoretical courses of physics, electronic and math ( for Licence, Master, engineer’s schools…).
