Durable, easy-to-use Gaussmeter for something different

The GM07  is our entry level Gaussmeter. With a Transverse Hall Probe as standard, the GM07 is suited to a wide range of applications where there is no requirement to export data from the Gaussmeter. 

  • DC accuracy of better than ±0.5% standard probe and Gaussmeter
  • Standard sensitivity Transverse Hall probe included
  • Range of Axial, Transverse, High Sensitivity and Fluxgate probes available to allow and extremely wide range of measurement 
  • Visible sensor point on probe
  • Intuitive menu set-up with non-volatile memory
  • Store measurements, up to 100 at a time
  • Dot matrix display with menu driven functions
  • Powered by 4x AA cells
  • UK Delivery: 5 to 7 working days from purchase
  • EU and Rest of World Delivery: 7 to 10 working days from purchase
With a Hirst Gaussmeter, you can rely on a product that has been developed with durability, precision and usefulness as core qualities. The GM07 is robust enough for rugged shop floors and accurate enough for laboratory use. With a one year guarantee and calibration certificate included, the GM07 Gaussmeter is ready to use and simple to operate.

Some example applications include:

  • Computer disk Drive Actuators
  • Loudspeaker Air Gaps
  • Electric Motor air gaps
  • Magnetic ‘strength’ testing for food industry separators
  • Spot checking magnetic field strength for Non-destructive testing (magnetic particle inspection)
  • Verifying compliance with IATA, IACO and FAA regulations on magnetism from packages to be shipped by air with AFG100 Fluxgate probe
  • Non destructive Testing (Magnetic) with Robust option TP002R
  • Goods inward and Quality Assurance Inspection
  • Magnet calibration
  • Transformer Stray Field measurements
The GM07 is ideal for a wide range of applications. If you do not see your desired application on the list, or to ensure the GM07 is right for you, please do not hesitate to contact us

The GM07 is a basic version of the GM08 Gaussmeter. Without external connectivity or the ability to connect to PC, the GM07 is a hand-held Gaussmeter with a wide range of functions and applications at great value. 

The GM07 comes with the TP002 Transverse Hall Probe, however, you may need an additional probe to suit your application. See our range of transverse and axial probes here.

With Hirst products, you can expect excellent reliability and accuracy. During manufacture, the accuracy of nuclear magnetic resonance is used to determine the irregularities and non conformities of the GM07 and GM08 with the Hall Probe. This is stored and used mathematically to automatically correct readings taken by the GM07 and GM08. This enables very linear and accurate measurements to be obtained. Every GM07 and GM08 comes with a certificate of calibration valid for one year.
