The MPT DAS-1 Electrical Impedance Tomography System is a fully autonomous, integrated induced polarization (IP) system, with 8 channels and a 24-bit A to D converter per channel. It is capable of collecting 3-D subsurface images using Electrical Resistivity Tomography (ERT) or Electrical Impedance Tomography (EIT).

This system has three different acquisition types:

Time Domain
Frequency Domain
Data Stream Mode

In TIME DOMAIN mode the system collects IP data using 1 to 35 user assignable windows at base frequencies from 1/64 hz to 9 hz.

In FREQUENCY DOMAIN mode the system can acquire phase and amplitude data from 1/64 hz to 5 hz.

The DATA STREAM MODE allows the user to store incoming data streams of up to 128 points and then apply their own data averaging and noise rejection methods.

The data are stored in ASCII format on microSD cards in standard FAT32 format allowing easy storage and transfer of up to 8 gigabytes of data. All of the data modes and system functions can be operated under PC control or autonomously.

The MPT system easily interfaces with ERTLab 3-D inversion software which allows three-dimensional topographical modeling and inversion, creation of 2D and 3D arrays/schedules of electrical resistivity measurement and a powerful graphical environment for displaying resistivity and IP models.
