Full Wave DC Electrical Method Instrument
With years of experience in developing and producing advance electrical method instruments, we develop full wave DC electrical instrument, a new generation multifunction DC electrical method instrument with the latest electronic technologies, e.g. full wave recording of current and potential, 32bit A/D, high power control, embedded real-time operation system and FPGA etc. The volume and weight of the instrument are obviously reduced. The main technical indexes and functions are top in the world compared with the similar instruments. The instrument can obtain better raw data in complicated environments than other similar instruments. Full wave DC electrical instruments are widely used for exploration of metal and nonmetal mineral resources, detection of underground water and geothermal resources, search for hidden defects in dam foundation and dike, investigation of tunnels of highways and railways and urban geophysical prospecting.
