Product Details

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.

Aquameter CRM - 20 : Low power version (4W) suitable for high resistivity soil.

Aquameter CRM 500 : High power version (40 W) suitable for saline & marshy terrain.

Aquameter CRM AT : It is in it's final stages of development. Essentially it is a more advanced version of CRM 500.
