ZZ Resistivity Imaging Pty. Ltd.


About us

Our FlashRES Resistivity/IP resistivity meters provide:

-Total flexibility of resistivity/IP method applications,

-Over six times the available channels which provide over six times faster surveys,

-Multiple configuration measurements in a single survey provide further time-saving in the field,

-Real-time readout of current and voltage measurements to facilitate on-site debugging.

ZZ is a South Australian-based geophysical instrument manufacturer. We specialise in the development of 61-channel resistivity and IP meters and 2.5D inversion software.

Our geophysicists are highly regarded in the academic sphere. We hold an extensive understanding of how resistivity/IP methods work, and our organisational culture promotes professionalism and goodwill. We intend to become the problem-solver for our customers. While taking care of your order, we also manage your practical problems faced in near-surface exploration.


ZZ Resistivity Imaging Pty. Ltd. (ZZ) was founded in 2006 by two near-surface geophysicists from the University of Adelaide.  After years of research and development, the first 61-channel resistivity and IP meter in the world was successfully developed, the FlashRES-64. After an extended period of continued refinement, we proudly launched our new FlashRES-UNIVERSAL range in 2013. In 2014, we released our 3,000W/1,200V booster transmitter - FlashRES Power Booster. FlashRES resistivity meters are now widely used in many research institutions, universities, and geophysical survey companies around the world.
