Digital Gaussmeter GM07 

Durable, Portable & Easy to Use 

The GMO7 Gaussmeters have been designed and manufactured by Hirst Magnetic Instruments Ltd. A company with more than 50 years experience in Magnetic Measurement. This experience together with their extensive knowledge of the magnetics market has enabled to design an instrument incorporating all the measurement functions a user is likely to need. The GMO7 is controlled via a simple menu and is supplied with a thin semi-flexible Transverse Hall Probe suitable for all but the very smallest applications.


  • Portable, Battery Operated, Handheld Device
  • Fast responses with digital stability (fast pulse / no drop in readings)
  • Graphical LCD Display
  • Menu Driven
  • DC, AC Peak, Max, Hold and Store Functions
  • Operating Function and Unit Displayed
  • Thin Semi-Flexible Probe
  • Visible Measurement Point

Measurement Functions:

The GM07 can measure:

  • DC: DC Magnetic Field Measurement
  • DC Peak: Maximum Positive Peak Reading of the DC Field
  • AC RMS: True RMS (Root mean Square) of Input Signal
  • AC MAX RMS: Maximum True RMS (Root mean Square)
  • AC Peak: Maximum Positive Peak Reading of the AC Field

Measurement Units:

The GMO7 can measure in Tesla, Amps/m, Gauss or Oersted. Saved readings can be automatically converted between measurement units.

Data Capture:

The GMO7 can HOLD measured values by pressing the Hall Probe button. Pressing the button again releases HOLD (when enabled).

The GMO7 can also STORE up to 100 measurements. These values can later be RECALLED, either on the Gaussmeter or via USB/RS232 with
the GMO8.


The GMO7 has a number of utility options allowing the operator to disable or select various times for the automatic POWER DOWN. Nulling routines may also be selected.

The GMO7 also has the ability to operate its menu structure in English, French, Spanish, Italian, German and Portuguese.
