MAE - Model ET300 -Multichannel Georesistivimeter 24-48 channels
The main feature of this instrumentation is the maximum versatility of use combined with the high speed of execution of surveys, both 2D and 3D. ET300 is managed via a normal laptop or tablet via USB connection. It is equipped with the "preview" function which allows the user to visualize a preview of the pseudo-section derived from the train of data just acquired directly in the field. The use of this function allows the operator to immediately verify the logged data. The instrumentation carries out the measurement or the measurement cycle set by the user in automatic mode. Once the measurement cycle is concluded, the acquired data can be immediately displayed using the "preview" function, the use of which allows the operator to immediately check the recorded data and process it with the relative data processing software.
STRENGTHS
- Parallelization of measurements for pole-dipole, pole-pole, dipole-dipole and three-dimensional configurations
- 24-bit resolution
- Pseudosection in real time
- ET30024 - RESISTIVIMETER 24 CHANNELS
- ET30048 - RESISTIVIMETER 48 CHANNELS
- Dramatically reduce the time it takes to complete a survey.
- Possibility of tackling investigations that were previously unthinkable, due to the high number of measures required
- Possibility of repeating the measurements several times to minimize the uncertainty, for the same time taken
- Lower energy consumption
- Recording of the standard deviation for each measurement
- Graphical representation with error bars of the measuring points
- Real-time visualization of the pseudo-section of resistivity
- Availability of an automatic repetition function of the measurements with an error percentage greater than a configurable threshold.
