Second-hand EM31-MK2: Conductivity Meter
The EM31-MK2 Ground Conductivity Meter maps soil materials, groundwater contaminants or any subsurface feature associated with changes in conductivity. We recently decided to sell a second-hand EM31-MK2 to renew our park.
The EM31-MK2 uses a patented electromagnetic inductive technique that allows measurement without any requirement for either electrodes or ground contact. With this inductive method, surveys can be conducted over any surface conditions, including those with high resistivity materials such as sand, gravel and asphalt.
Ground conductivity (quad-phase) and magnetic susceptibility (in-phase) measurements are recorded directly onto an integrated Archer field computer. The field computer provides many features for enhanced data collection including Bluetooth wireless communication, GPS compatibility, real-time data graphics, and compatibility with Windows Mobile applications.
The effective depth of exploration is about six meters from the instrument, making it ideal for environmental and engineering site characterization.
Important advantages of the EM31-MK2 over conventional resistivity methods include:
- speed of operation
- continuous data collection
- high spatial resolution of data
- the precision with which small changes in conductivity can be measured.
We propose second-hand EM31-MK2, sold with an Archer data logger. This equipment was made in 2011 and it is in good shape. Please do not hesitate to contact us for any further information you may require.
