Key Feature of 2D/3D Resistivity Tomography 2D IP Imaging Survey Equipment Geophysical Exploration Equipment
High power, wide range, high precision: max power up to 9000W (1500V*6A), voltage input range is 160Vp-p, high measuring precision of small signal (voltage is less than 0.1mV and current is less than 0.1mA with ±1% measuring precision);all of which make WDA-1/WDA-1B mainframe an ideal device for regions of high resistivity and to achieve better measured results.
Multi-functional: voltage/current range and small signal accuracy are improved greatly, which makes it applys with rock sampling tester, high-power IP receiver, general electrical method instrument, IP instrument, water detector, multi-electrode 2D/3D electrical imaging instrument, etc.
Various measuring parameters, wide applications: it is available to measure data of voltage (VP), current (IP), apparent resistivity (ρs), Self-Potential (SP), apparent polarizability (M~M7), metal factor (G1~G7), half decay time (TH), deviation (r), induce polarization ratio (J) and voltage decay curve, etc.
Bluetooth technology, wireless remote control: Bluetooth technology enables the tablet PC to control the WDA-1/WDA-1B mainframe in 10 meters. It enables all operations as set parameters, start measurement, display result and save data more easily.
Tablet PC operate, powerful function: all operations as parameters setting, data display, data storage, curve drawing all be finished on the tablet PC, easy and visuable for filed data procession.
