A Tesla meter, also known as a gauss meter or magnetometer, is a device used to measure the strength of magnetic fields. It typically measures the magnetic flux density in units of Tesla (T) or Gauss (G), depending on the model and settings. Tesla meters are commonly used in various fields such as physics, engineering, geology, and medicine to assess and monitor magnetic fields produced by magnets, electric currents, or other sources.
TM5100 is a portable, multi-functional magnetic field measuring instrument, suitable for measuring the surface magnetic field of permanent magnet materials, residual magnetism of mechanical parts, DC constant magnetic field, magnetic separators or iron removers, etc. It can be used as a basic magnetic parameter measuring instrument in magnetic material manufacturers and application units, machinery manufacturing companies, university scientific research units, etc.
TM5100 Tesla Meter offers a range of 2mT to 3000 mT with selectable accuracy of 1%, 2%, and 5%. It allows unit switching between G, mT, and A/m, and includes features like one-key reset, max hold function, and N/S polarity display. Additionally, it features backlight support, battery power display, optional axial and radial probes, USB interface, and optional magnetic shielding cavities.
Inserting the male connector of the probe into the female connector on the top of the Gauss meter, make sure that the convex point of the probe female connector matches the groove of the Gauss meter male connector as shown in the Figure 1.

When removing the probe, pinch the position as shown in the Figure 2 and pull out the probe female connector.

Figure 3: Schematic diagram of basic measurement steps
No. | Step | Description |
1 | Power on | Press the power switch button, start to warm up for 3 minutes |
2 | Remove the probe cover | As shown in the second step of the above figure: 1. Pinch the probe handle inside the red frame with one hand and the probe cover with the other hand; 2. Rotate the probe cover in the direction shown in the figure (or the direction marked on the probe cover); 3. When rotating to the point where it cannot be rotated, pull out the probe cover to remove it. |
3 | Zeroing | Move the probe away from the magnetic field (or put it in the magnetic shielding cavity), observe the screen to see if the display is 0.0mT. lf it is not 0.0mT, press Zero button to reset. |
4 | Testing | Place the probe in the magnetic field to be measured and close to the specimen surface (make the direction of the magnetic field perpendicular to the TEST surface of the Hall probe), and read the magnetic inductionvalue after the value is stable. see 3.4.3 for details.If you want to find the maximum value, press the Hold button toautomatically hold the maximum value. |
Figure 4: Notes on the use of radial Hall probe
When measuring permanent magnets, the Hall sensor should be placed as close to the surface of the specimen as possible. The farther away from the sample, the greater the attenuation of the magnetic field and the smaller the measured value. As shown in Figure 4 above.
When the Hall chip is close to the sample, do not press it with force, otherwise itmay be damaged, as shown in Figure 4 below
Figure 5: The difference between radial/axial probe
The radial Hall probe measures changes in the magnetic field perpendicular to its axis, commonly used for measuring rotating or planar magnetic fields. The axial Hall probe measures changes parallel to its axis, often used for measuring axial magnetic fields or magnetic flux.
For TM5100 Tesla Meter, the radial Hall probe is an standard accessory, while the axial Hall probe is optional.
