DC Gaussmeter Model GM1-HS


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

Product Documentation


SKU: GM1HS Category:


Product Description:
The Model GM1-HS measures the strength and polarity of magnetic fields up to 799.99 gauss. The thin sensor is 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 0.01 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.

Comes with NIST traceable calibration certificate. Yearly calibration service available from AlphaLab Inc.


  • High dynamic range and sensitivity: reads up to 799.99 gauss with 0.01 gauss resolution including polarity
  • Instant on, updates four times a second, with 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 are included
  • CE Compliant
  • Certificate of NIST traceability included
  • Detachable Rubber Boot Included


  • 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.
