ERA-MAX ELECTRICAL EXPLORATION SYSTEM

ERA-MAX equipment is designed for electrical prospecting on any surface

Features

•Low-frequency electromagnetic method for measuring resistivity

•Operating frequencies: DC, 1.22, 2.44, 4.88, 9.76, 19.52 and 625, 1250, 2500 Hz

•Electrical field can be measured by pairs of active electrodes capacitively coupled to the earth, or by the telescopic antenna in air

Applications

•Civil-engineering survey for construction and inspection of active pipelines, roads, hydraulic facilities

•Search and exploration for ore and nonmetallic minerals

•Ecology, archeology

•Inspection of house footing and urban underground utilities

Survey methods

•Electrical exploration - resistivity method (vertical electrical sounding profiling)

•Charge method

•Self-potential method

•Inductive methods

•Geomagnetics - vector measuring of the earth magnetic field

•Noncontact probing of protective currents in pipelines
