POLARES 2.0 electrical imaging system for tomography makes use of innovative technology based on Alternate Current (AC) to simultaneously measure and display all survey parameters: soil resistivity, current, voltage, self potential, standard deviations and induced polarization. Measuring up to 6 scans/sec, it guarantees maximum speed and accuracy in the acquisition of measurements in work, regardless of the type of spreading used (as opposed to traditional DC-based multi-channel systems). Compact, simple and intuitive, easily managing all multi-electrode array configurations for the measurement of apparent resistivity: Schlumberger, Wenner, Dipole-Dipole (user defined configurations are also available through Utility Software delivered with the instruments).
Equipped with an automatic “multiplexer” to commute signals on the different electrodes, the instrument can measure both current and voltage with microprocessor-controlled sequence of measurements. Both the control and measuring system and the power system are set inside the same carrying case. Only the battery and the commutation system are external. POLARES 2.0 is lighter, smaller, faster and more reliable than the previous generation of electrical imaging systems. Thanks to an intuitive user interface, realised through a high-quality LCD touchscreen, all operations can be controlled without a mouse or a keyboard. Its very low consumption embedded system, equipped with “open source” software operating system, and its solid-state memory ensure the greater reliability of this instrument.
Various external devices can be connected through the USB interface, such as data storage media, network interfaces, WiFi, Bluetooth, GPS antennas, keyboards and more. The use of a robust industrial-type PC ensures instrument operation even in extreme environmental conditions, considerably extending the temperature and humidity range of use.
