'The super gradiometer adopts the latest technology, with a sensitivity of up to .@ and a stability of better than /year. It is specially designed to capture weak earthquake precursor information and other weakly changing magnetic field information.
'Advantages:
'
' In seismic research, when the distance between two sensors of a horizontal gradiometer is set to , its sensitivity can reach /. Additionally, noise is minimized. This advantage makes other measurement methods (such as electromagnetic methods) difficult to match. Note: It is the frequency unit of seismic piezomagnetic signal.
