IESE-SONDI

IESE's services and instrumentation arm, IESE-SONDI, was founded in 2007 when UniServices acquired SONDI and Consultants.  Established in 1989, SONDI specializes in custom geophysical exploration projects and surface and borehole geophysical instrumentation. IESE-SONDI has more than 30 years experience in designing, building, and deploying long-term and permanent borehole instrumentation. All equipment is designed and manufactured in IESE's seismometer laboratory at the The University of Auckland.

 Borehole Seismology

The core of IESE's borehole seismic networks are the S2-2 and S2-4.5 Borehole Seismometers:

 S2-2

 S2-4
