Electromagnetic Geonics EM-39 Conductivity - Gamma Logger

The EM39 provides measurement of the electrical conductivity of the soil and rock surrounding a borehole or monitoring well, using the inductive electromagnetic technique. The unit employs coaxial coil geometry with an intercoil spacing of 50 cm to provide a substantial radius of exploration into the formation while maintaining excellent vertical resolution. Measurement is unaffected by a conductive borehole fluid or the presence of plastic casing. The instrument operates to a depth of 500 metres.

Included: 

Digital control unit
Depth Encoding Wheel on tripod
Hand-crank winch w/100m cable
Induction probe
Gamma Probe

The EM-39 interfaces to digital logging devices, but does not include one. Customers may log into their own laptop or order an optional logging computer.
