Gaussmeters are scientific instruments used to measure magnetic fields. AlphaLab carries a full line of hand-held, digital gaussmeters for scientific and industrial applications, that can measure DC and AC magnetic fields, as well as magnetic pulses. Measurements can be single-axis or 3-axis, with USB data logging and can range from 0.01 milligauss up to 30,000 gauss, depending on your application.

Measures vector components (X, Y, Z) and magnitude of static magnetic field with USB datalogging.
Every MR3 includes:
The Gaussmeter Model GM1-HS reads moderate-strength static magnetic fields up to 800 G with a resolution of 0.01G. It measures magnetization of ferrous metals, solenoids and the far field of strong magnets
Comes with:
The Gaussmeter Model GM1-ST measures the field of even the strongest magnet (to 20kG) down to fine resolution (0.1G). Features rapid turn-on and fast update.
Comes with:
Three-axis vector probe for the GM330 gaussmeter—three X, Y, Z sensors read all field components at once and report true magnitude regardless of orientation, plus a configurable button for Freeze, Data Collection, Peak Hold, and Autozero.
Choose it when the field direction is unknown, changing, or awkward to chase by hand—no aligning the probe to get an accurate reading.
Dedicated axial probe for the GM330 Gaussmeter—a rigid, single-axis design that reads the field along the probe axis with repeatable angular precision, plus a configurable button for Freeze, Data Collection, Peak Hold, and Autozero.
Choose it when your measurements are consistently axial—reaching into bores, coils, and solenoids where a fixed sensor orientation matters.
Universal flex probe for the GM330 Gaussmeter—measures both transverse and axial fields, with a configurable button for Freeze, Data Collection, Peak Hold, and Autozero.
Our default recommendation when you’re not sure which probe your application needs.
Thin transverse probe for the GM330 Gaussmeter—a slim, rigid tip that reads the field across the probe face for gap measurements, plus a configurable button for Freeze, Data Collection, Peak Hold, and Autozero.
Choose it when you’re measuring inside narrow gaps—between magnet poles, in motor or speaker air gaps, and across slots down to 0.65mm.
The MagWave, a fast magnetic waveform sensor, is intended to display pulses of magnetic field (one axis of the field) on an oscilloscope (not included). It accurately converts magnetic signals into voltage signals in real-time.
These capabilities make the MagWave an ideal instrument for measuring the output from PEMF generating equipment or other rapidly changing magnetic sources.
Laboratory gaussmeter that reads AC/DC magnetic fields, true peak field, has an alarm and USB datalogging. Maximum range is 30,000 gauss. Select 1 probe that is included in the cost of the meter. You can select more probes for your GM2 by returning to the GM2 Product Family page after adding a GM2 to your cart.
Laboratory gaussmeter that reads AC/DC magnetic fields, true peak field, and total field magnitude, with a configurable alarm and onboard SD-card data logging. Accepts both single-axis and true 3-axis probes, with a maximum range of 30,000 gauss.
Every GM330 includes:
Displays X, Y, Z and magnitude, for rapid magnetic field measurements, such as mapping the MRI fringe field (including the 5 gauss line) and scanning for residual magnetism. Displays the field values, with a user selectable sound and light alarm and USB datalogging. Maximum range is ±799.99 gauss.
This meter is used to verify compliance with IATA, IACO, and FAA regulations on magnetism from packages to be shipped by air.
This meter reads weak DC magnetic fields down to 1 nT (.01 mG) with a range of 2 Gauss.
The AC Milligauss Meter UHS2 is a professional-grade instrument for high-precision measurement of AC magnetic fields. It resolves fields down to 0.01 mG across a 13 Hz – 75 kHz bandwidth and reads true 3-axis magnitude regardless of orientation. Every unit ships with a NIST-traceable calibration certificate, making it well suited to EMF/EMI surveys, electromagnetic-pollution investigations, and other work where accurate, documented readings matter.
The Earth Magnetometer Model EM2 measures the Earth magnetic field with a resolution of 1nT (1 gamma). This resolution is about 0.002% of the typical Earth field strength. It is used to locate buried magnetic objects or materials.
Used to “zero” probes for gaussmeters, the ZGC has a built-in degausser and can achieve < 0.002 gauss in a typical external field.
