Earth Resistivity Meters
 1) Earth Resistivity Meters-
      Aquameter CRM
 
Resistivity (geo-electrical) surveying is one of the most versatile and successful geophysical prospecting methods for mineral prospecting, ground resistance measurements, geological and geo-technical mapping, bedrock studies, certain civil engineering applications and also for ground water prospecting.
 

The Aquameter's intelligent microprocessor technology employs ingenious methods for extracting subsurface information. It is a popular instrument, because of its single button operation, deep penetration, accurate and reliable results, even in adverse field conditions. The instrument has a facility to measure self potential (SP) which is useful in mineral prospecting and environmental studies.
