Microcomputer Induced Polarization Receiver - GWM00372

Applications

This is a micro-computerized time domain induced polarization receiver designed for high productivity surveys in engineering geology, metallic and nonmetallic mineral exploration, and groundwater investigation.

This instrument has the ability to measure multiple parameters directly, including self-potential, primary potential and polarizability. It can be widely used for metallic and non-metallic deposits investigation, groundwater resources detection and engineering geological exploration.

this Microcomputer Induced Polarization Receiver can be used not only for induced polarization survey but also for resistivity survey. In addition to standard surface measurement, this also can be applied for continuous induced polarization logging and borehole induced polarization measurement.
