The EM31 maps geological variations, groundwater contaminants or any subsurface feature associated with changes in the ground conductivity using a patented electromagnetic inductive technique that makes the measurements without electrodes or ground contact.

EM31 is a Windows Mobile based, button and dialog driven program designed to be simple to use. Although the program fully supports touch creen interface, the keyboard entry available in Allegro MX may be used in field applications. The EM31 can be full

The EM31 and EM38 are used for different applications because of the difference in intercoil spacing, which affects the effective depth of exploration. The EM31 has a coil spacing of 3.7 meters that allows it to reach depths of approximately 6 meters in the vertical dipole mode and approximately 3 meters in the horizontal dipole mode.

The Geonics EM31 is a one-man portable instrument designed for engineering geophysical applications down to depths of the order of six meters. The intercoil spacing is fixed at twelve feet (3.66 meters).

We offer EM31 CMD Electromagnetic Conductivity services to identify subsurface features related to soil conductivity & resistivity.
