GM2 Gaussmeter Product Family

The GM2 is a laboratory-class gaussmeter that measures both AC and DC magnetic fields with an exceptionally wide dynamic range — from a maximum of 30,000 gauss down to 0.1 gauss resolution with an ST Probe, or a max of 800.00 gauss down to 0.01 gauss resolution with an HS probe. It reads DC field, AC field, and peak field, with a fast 2-millisecond peak-hold that captures brief transients most meters miss. A configurable alarm sounds when the field exceeds a threshold or falls between two limits you set, making it well suited to scanning parts for residual magnetism or checking magnets against spec.

The meter automatically detects its probe, and a full range of interchangeable probes is available in standard and high-stability series and multiple tip shapes — so the GM2 adapts to everything from strong permanent magnets to fine, low-field work. Every GM2 ships ready to use with one probe of your choice, a 9-volt battery, USB cable for data logging and power, an analog output jack, and a NIST-traceable calibration certificate.

It’s a practical, fast, intuitive instrument for R&D, manufacturing QC, and aerospace applications. Choose your included probe below, then add additional probes and accessories to complete your setup.
