The GM08 Gaussmeter is the best device for those needing to measure magnetic field strength and magnetic flux density regularly on a daily basis, or those who just wish to take the difficulty out of reporting procedures.
With a GM Gaussmeter, you can rely on a product that has been developed with durability, precision and usefulness as core qualities. The GM08 is robust enough for rugged shop floors and accurate enough for laboratory use. The ability to drive the GM08 via PC also means you can use the Gaussmeter as a desktop device or quickly download or upload data with minimum hassle. With a one year guarantee and calibration certificate included, the GM08 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 Nondestructive 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 Rugged Transverse Probe option TP002R
• Goods inward and Quality Assurance Inspection
• Magnet calibration
• Transformer Stray Field measurements
• Measuring 5 gauss lines for hospital based MRI (NMR) devices

The GM08 is ideal for a wide range of applications. If you do not see your desired application on the list, or to ensure the GM08 is right for you, please do not hesitate to contact us.

The GM08 is an advanced version of the GM07 Gaussmeter. With external connections and the ability to connect to PC, the GM08 is a hand-held Gaussmeter with a wide range of functions and applications at great value. 

The GM08 comes with the TP002 Transverse Hall Probe as standard, however, you may need an additional probe to suit your application.  

GM08 Features 

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

Remote PC control – The GM08 offers the unique ability to remote -control the Gaussmeter through a PC via USB or RS232

Non-Volatile memory – Any settings and recorded measurements are automatically stored to ensure that every time you switch the Gaussmeter on, it is ready to use with the same settings as previously used.

Holding and Storing measurements – a unique feature on the GM08 allows users to HOLD or STORE measured values. Users can set the hold or store functions in GM08 menu and press the conveniently situated button on the Hall probe to capture the reading without looking away from the area of concentration. In the STORE setting, The GM08 can record up to 100 measurements. These values can later be RECALLED, either on the Gaussmeter or via USB/RS232 with the GM08.

Easy reports - The GM08 has the added advantage of storing and uploading not only the measured values, polarity, measurement units and measurement function, but also the time at which the measurement was taken. Data can easily be downloaded to excel, open office spreadsheets, or to a CSV format file, taking the hassle out of creating records.

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

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

Accuracy

With 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 GM08 and GM07 with the Hall Probe. This data is stored and used mathematically to automatically correct readings taken by the GM08 and GM07. This enables very linear and accurate measurements to be obtained. Every GM08 and GM07 comes with a certificate of calibration valid for one year.

Software 

Specialized software comes as standard on CD with your Gaussmeter pack. It can also be downloaded. The software, which is compatible with Windows, allows the user to control the Gaussmeter remotely, export measurements and stored data via USB or RS232 interfaces. Data can be exported to Excel or OpenOffice spreadsheets or to a CSV format file.
