Hirst GM08
Hirst GM08 Gauss Meter
Tangential Field Strength Meter
The GM08 improves on the earlier GM07 - With the GM08 including all the features found in the GM07 but with new PC interface features included as standard if operators should choose to use them.
The GM08 Gaussmeter is ideal for those needing to measure magnetic field strength and magnetic flux density in everyday applications like NDT and is suited with lab work as the GM08 has a range of interfaces to connect to PCs, ADCs and Oscilloscopes via the analogue output.
With a Hirst Gaussmeter, you can rely on a product that has been developed with durability, precision and usefulness as core qualities. 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 a one-year guarantee and calibration certificate included, the GM08 Gaussmeter is ready to use and simple to operate.
Designed for factory floor, on-site and laboratory measurement of Magnetic flux Density and Magnetic Field Strength.
The GM08 Gauss Meter is supplied with a Transverse Hall Probe as standard - Axial Probes available on-request.
NDT Gauss Meter
Gauss meters are used in many industries to monitor magnetic fields on-site.
In Non-Destructive Testing (NDT) Gauss meters are commonly used to verify the strength of magnetizing fields in Magnetic Particle Inspection (MPI) to ensure enough magnetic flux is being generated. If insufficient magnetic flux is present this may result in defects being missed by operators.
However Gauss meters are used extensively in other sectors including aerospace, motorsport, power generation, nuclear sectors and general manufacturing for a wide range of applications.
PC Interface
- 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.
