DC Gaussmeter Model GM1-HS

Manufactured in the USA by AlphaLab, Inc.



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. This model supersedes the MD1-HS, which had no auto-zero.

Available Options:

Detachable Rubber Boot: $15   Hard Carrying Case: $18   NIST Traceable Certificate: $30

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 .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. For a 3-axis meter, see the Vector Gaussmeter Model VGM.
