The EM38-MK2 Conductivity Meter measures both quadrature-phase (conductivity) and in-phase (susceptibility) components with two receiver coils. This instrument is perfectly suited for shallow monitoring of ground water pollution, mapping saline intrusions, mapping buried foundations and determining topsoil thickness.
The instrument includes two receiver coils, each orientated with vertical dipoles, separated by 1m and 0.5m from the transmitter, offering two effective depth ranges. It is also possible to operate the instrument on its side (horizontal dipoles) changing the effective depth ranges. The EM38MK2 is designed to be particularly useful for agricultural surveys measuring soil salinity, and can cover large areas quickly without needing grounded electrodes. Very lightweight and only one metre long, the EM38MK2 provides rapid surveys with excellent lateral resolution. The instrument offers data transmission to a field computer via Bluetooth (10m range) allowing more flexibility during data collection. Data can be positioned by connecting a GPS receiver to the Archer data logger. New coil technology, supported by temperature compensation circuitry, markedly improves temperature–related drift. An optional, collapsible calibration stand supports automation of the instrument calibration.
