Geovizer
The multipurpose compact profiler “Geovizer” implements the method of induction multi-frequency sounding, and allows you quick and contactless measuring of the underground situation. As a result of research, it is possible to obtain the spatial distribution of the level of the secondary signal from the ground till 3 meters depth. The signal level allows for estimation of resistivity. High contrast targets such as – metal objects, cavities, watering with highly mineralized solution could be successfully localized in possible conditions. Also good targets – objects with high conductive (tunnels, bunkers with wet walls, pipes, etc.) thats lay in low conductive soil.
Three-frequency EM-I profiler “Geovizer” allows profiling on any set of 3 fixed frequencies in the 12.5 – 111 kHz range, including the automatic linking of the measuring point to global coordinates. The overall dimensions of the device (750 x 650 x 340 mm), weight (4.5 kg) and ease of management via a smartphone based on the Android operating system – all this greatly simplifies the process of data collection, and also increases the spatial resolution of the measuring.
Preliminary results of measurements with “Geovizer” are visualized in real time on the smartphone display. Special software for smartphone allows you to build quasi-three-dimensional representations of the signal distribution.
Connection to the device is carried out according to the BlueTooth protocol.
Main features:
– Low weight and overall dimensions;
– Ability to perform air calibration;
– Advanced features of QZond / iiSystem software: calculation of App.Resistivity, signal phase.
