The new EM38-MK2 Ground Conductivity Meter effectively combines the performance features of all previous EM38 models in a single instrument: The EM38-MK2 provides measurement of both the quad-phase (conductivity) and in-phase (susceptibility) components, within two distinct depth ranges, to a maximum effective depth of 1.5 m, all simultaneously. In addition, new standard features and options each provide additional benefits: integrated Bluetooth functionality provides the option of wireless data transmission; a power input connector allows for the use of external power sources; a rechargeable external battery pack extends the duration of instrument operation; and a portable calibration stand provides the convenience of an automated calibration.
