Notes: n.a. means “not available”. All meters use a Hall-effect type of probe.
[a] Resolution is Least Significant Digit. 1X, 0.01X, or 10X is resolution compared to standard probe, 0.01X is finer resolution.
[b] Accuracy shown is for measuring a weak DC (static) field. The ±error shown would be larger when measuring a strong field. AC field error may be larger than the DC error shown. For complete specifications see manual.
[c] For best accuracy for Low-field probes: probes MOS51 and MOS81 are designed for use in a volume of uniform magnetic field around the probe at least 7000cc (0.25 cu.ft): for example a cylindrical volume 10cm (4") radius x 22cm (9") long, and MOS probes frequency response is DC to 700 Hz (-3dB point).
Low-field probe MOX81 is designed for use in a volume of 84 liters (3 cu.ft) of uniform magnetic field, and MOX81 frequency response is DC to 400 Hz (-3db point). MOX81 also requires use of large zero-gauss chamber YA-112 sold separately.
Conversion from A/m into Tesla or Gauss for measurements in air or free space:
1 kA/m = 1.26 mT = 12.6 G
1 A/m = 1.26 uT = 12.6 mG
The magnitude of the Earth's magnetic field at its surface ranges from 0.25 to 0.65 gauss, (0.025 to 0.065 mT), (250 to 650 mG), (25 to 65 μT).
For gaussmeters to measure AC magnetic fields only: see AC Gaussmeter tab at top of page.
