- Immediately displays the DC or AC magnetic field.
- Warm-up time is only 1/2 second, and there are no initial calibrations or adjustments required. Operates on a 9V battery or AC adapter (110-240 VAC), so the meter can be left permanently on if required.
- Can be rapidly scanned across a part to check magnetization.
- An alarm sounds only where the field magnitude exceeds the level that you set or where the field is between two levels you set. The alarm response time is 2 milliseconds, so it can be scanned quickly. The alarm can be used either to check for any residual magnetism or to sound if a magnet is out-of-spec (by setting the upper level just below the minimum acceptable field).
- When set to the Peak/Hold mode, it displays the maximum field encountered since the last time “Reset” was pressed.
- The Peak/Hold response time is also 2 milliseconds, so after scanning a surface, the meter can detect and display any very brief peak (spike) that was encountered as well as a slow one. The peak displayed includes the polarity sign, and the value will be held in memory until you reset it or turn off the meter.
- Offset, if required, is manually adjustable.
- There is also a “Relative Zero” function. Several interchangeable probe types are available, and the meter automatically detects the probe type.
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, the 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.

- There are two series of probes: ST (standard; 0.1 gauss resolution below 20 kilogauss, but with 30 kilogauss maximum range), and HS (high-stability; 0.01 gauss resolution with 799.99 gauss range).
- Each series is available in three shapes: universal, axial, and transverse.
- The universal can be bent (thousands of times if needed) between an axial shape (which measures the field component parallel to the cable direction) and a transverse shape (which measures the component parallel to the thin dimension of the probe).
- The standard universal probe (whose tip is shown in the image above) is included with the meter, but another series/shape can be substituted. Each probe is at the end of a 100cm flexible cable.
