designers & manufacturers of Microprocessor based Earth Resistivity Meters.In geo-physical prospecting, the geo electrical (resistivity) method is used effectively for ground water prospecting, geological and geo-technical mapping, bedrock studies, agricultural and certain civil engineering applications, water quality studies and also in mineral prospecting. Aquameter is the most popular instrument in India for geophysical studies. It is based on the modern technology of microprocessors and employs ingenious methods for extracting subsurface information. What makes our instrument so popular is its simple operation, deep penetration, accurate & reliable results even in adverse field conditions. In addition, a considerable reduction in survey time proves a boon when working under hot sun. The instrument has a facility to measure Self Potential (SP) which is useful in mineral prospecting and environmental studies. We have 2 models – Aqua meter CRM 20 & CRM 500.
