Durable, easy-to-use Gauss Meter for spot-checking applications

The GM07  is our entry level Gauss Meter. 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 Gauss Meter. With a Hirst Gauss Meter, 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 Gauss Meter 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 Nondestructive testing (magnetic particle inspection)
  • Verifying compliance with IATA, IACO and FAA regulations on magnetism from packages to be shipped by air with FG01 Fluxgate probe
  • Non destructive Testing (Magnetic) with Robust option TP002R
  • Goods inward and Quality Assurance Inspection
  • Magnet calibration
  • Transformer Stray Field measurements

If you don’t see your desired application here – please rest assured that the GM07 is capable of a great many more uses. If you are not sure if it right for you, please don’t hesitate to contact us

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

The GM07 comes with the TP002 Transverse Hall Probe, however, you may need an additional probe to suit your application. Find out which probe you need.

 Accuracy

With Hirst products, you can expect excellent reliability and accuracy. For more details of what the GM07 is capable of, please check the Technical Specification Tab on this page.

During manufacture, the accuracy of nuclear magnetic resonance is used to determine the irregularities and non conformities of the GMO7 and GMO8 with the Hall Probe. This is stored and used mathematically to automatically correct readings taken by the GMO7 and GMO8. This enables very linear and accurate measurements to be obtained. Every GM07 and GM08 comes with a certificate of calibration valid for one year.

Repeatability ±0.1% Margin for change over repeated measurements
Traceability ±0.8% Calibrated to standards traceable to the National Physics Laboratory (UK)
Accuracy ±0.5% Margin of difference from true reading, probe AND Gaussmeter.

GM07 Features

The GM07 offers a number of unique functions at the touch of a button thanks to the simple menu format.

Unit Conversion – Measurements can be taken in any of the magnetic units. Saved and Held readings can be automatically converted between measurement units.

Non-Volatile memory – Any settings and recorded measurements are automatically stored so that every time you switch the Gauss Meter on, it’s ready to use for your specific requirements.

Holding and Storing measurements – a unique feature which allows users to HOLD or STORE measured values. Users can set the hold or store functions in the GM07 menu and press the conveniently situated button on the Hall probe to capture the reading without looking away from the area of concentration. Pressing the button again releases HOLD (when enabled). In the STORE setting, The GM07 can record up to 100 measurements. These values can later be RECALLED on the Gaussmeter.

Battery save – The operator can disable or select various times for the automatic POWER DOWN. Power downs always give warnings so they can be stopped.

Zeroing – When the Gauss Meter needs to be zeroed, a zero flux chamber and instructions are provided for easy nulling. Two simple routines can reset the Gauss Meter reading to zero or relative zero to the range you are on.

Support: Please ensure you have read the provided instructions and checked our support page before contacting us.

All that is required to ensure the continued accuracy of the GM07 is an annual calibration with the manufacturer. Other manufacturers and calibrators do not have the facility to fully reset the Gauss Meter. This will provide users with the annual calibration certificate and assurance that readings are within +/- 0.5% accuracy for a further 12 months.

Hirst like to share their expertise with users long after the initial purchase is made. Users can expect a range of support and maintenance services to ensure satisfaction.
