Notes:   n.a. means “not available”. 

[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
