Gaussmeters measure magnetic flux density. The vast majority of Gaussmeters use a Hall probe to measure magnetic flux density.
Gaussmeters offer a static measurement. The probe is placed in the desired measuring location and the Gaussmeter measures the flux density at that point. Each Gaussmeter is fully capable of measuring dynamic fields but it is not a requirement of the measurement process to have a changing magnetic field or environment.
Gaussmeters are excellent for measuring the flux density of air gaps in loudspeakers, motors etc. In these regions the flux density is uniform so probe position is less important. Gaussmeters are also excellent at determining local point effects as they have a very small detection area on the probe.
The Model SM-GM3 Measures the strength and polarity of magnetic field up to 30kG when using a standard probes, or 800 gauss (resolution 0.01 gauss) if an HS probe is used. Functions include DC, AC and peak hold along with a user-adjustable alarm which has three modes of operation. DC background field can be subtracted out either by pressing "Relative Zero" or by manually adjusting the offset. The meter includes battery, AC adapter analog output jack and calibration certificate. If a standard probe is used, resolution is 0.1 gauss up to 19,999.9 gauss, which is stronger than the field of any permanent magnet. This 5 ½ digit display allows measurement of tiny difference in strong fields. Above 20kG the meter autoranges to a 30kG range. Interchangeable probes are available at two sensitivity levels: standard to 30k gauss and HS (resolution 0.01 gauss); these are available in universal (bendable), axial and transverse shape. Choice of one probe is included with the meter.
High dynamic range: can measure even a small variation in a large DC, AC or peak magnetic field.
Programmable alarm will sound either if field exceeds a level you set or if the field is between lower and upper levels you set.
Intuitive to use with rapid turn on, fast update. Begin reading DC field, AC f field, or peak field just by turning the knob. No setup or calibration required
Peak hold function shows the highest DC level with fast 0.002 sec capture window; also displays polarity of the peak.
Interchangeable probes: range 30k G with ST probes; 800 G (0.01 G resolution) with HS probes
Runs on battery or AC adapter (included).
Includes analog output connector, certificate of calibration.
The ST-Probe measures all magnets, DC/AC electromagnets and solenoids. With the HS-Probe, parts can be rapidly scanned for residual magnetism. An alarm can be set to sound is any region exceeds a set threshold. "Peak hold" functions shows the maximum magnetism.
Measures background (including Earth) field direction and strength, both DC and AC.
Using the AC adapter, meter can be left on permanently to capture the peak field value (if at least 0.002 seconds in duration); can be read at any future time.
