Welcome to Zonge International

Zonge Engineering and Research Organization, Inc has changed its name to Zonge International, Inc. to better reflect the nature and scope of the company.

Still an Employee-Owned company with the same ownership and management, Zonge International continues to provide innovative geophysical field services and instrumentation, specializing in electrical and electromagnetic methods. Starting with minerals exploration in the 1970's, Zonge has since expanded into hydrological, hydrocarbon, environmental, engineering, and unexploded ordnance applications and extended our capabilities to include potential field and seismic surveys.

Zonge's success has been the result of a continuous commitment to the development of new geophysical tools and the integration of the Engineering and Field Service groups, leading to effective and innovative tools. The development of the receiver and transmitter systems has resulted in adaptation of these tools to numerous new applications and created the most versatile electrical and EM receivers available in the world today.
