    GM1-ST, DC Gaussmeter for Residual Magnetism, 0.01-800G

    The Gaussmeter Model GM1-HS reads moderate-strength static magnetic fields up to 800 G with a resolution of .01G. It measures magnetization of ferrous metals, solenoids and the far field of strong magnets.


    • High dynamic range and sensitivity: reads up to 799.99 gauss with .01 gauss resolution including polarity.
    • Turns on instantly, updates four times a second, no setup or initial calibration required.
    • Auto-Zero (subtracts the present field from subsequent readings); also a fine offset control.
    • Offset range is the full ±799.99 gauss.
    • 1% accuracy at room temperature.
    • Flexible probe and battery included.
    • Optional rubber boot and hard carrying case are available.
    • CE compliant.

    The Model GM1-HS measures the strength and polarity of magnetic fields up to 799.99 gauss. The thin sensor is located at the end of a 100 cm flexible cable. The sensor tip is also flexible and can be bent for a variety of situations. The sensor can be held against the surface of a steel part to check for residual magnetism, or it can be bent into an "L" shape to measure inside a DC Solenoid. This meter has a resolution of .01 gauss (1/50 of the Earth's typical field) which is finer resolution than the Model GM1-ST. It is also used to map fields from large magnets (If fields are over 800 gauss, use the Model GM1-ST). The meter has immediate turn-on and updates 4 times a second.
    There is no setup required, making this the fastest gaussmeter available.
    This is a 1-axis meter.


    • Makes detailed measurement of residual magnetism in metal parts.
    • Use to map field near a magnet, such as the 5 gauss line around an MRI machine.
    • Detect ambient field direction and strength, such as Earth Field.
