MicroMag USB Gauss Meter Magnetometer


SKU: USB-ST1 Category:


The USB MicroMag measures strength and polarity of magnetic fields up to 19,999 Gauss. The sensor can easily fit in a .060 inch (1.5 mm) gap and is at the end of a 100 cm flexible cable. The sensor end can be bent if required for a variety of situations. Place the sensor on a magnet face to measure the field.


  • High dynamic range (+/-19,999 Gauss)
  • 2% accuracy at room temperature, including probe
  • Interfaces with Windows 10 PCs


  • Measures all permanent magnets. (Maximum field of magnets is about 15,000, which occurs only with rare-earth magnets in a gap configuration.)
  • Measures inside DC Solenoids (probe is bent into “L” shape to measure this).



Range: ±19,999 G with polarity indicator
Resolution: 1 G
Accuracy: ±2% (-4° to 65°C)
Probe (non-detachable): 1.5 (thick) x 4.3 x 24 mm
