WDA-1/WDA-1B super digital DC resistivity/IP meter can conduct:
a) General resistivity/IP survey, in association with only one/two Current electrodes, one/two Potential electrodes, AB connecting wire, MN connecting wire and power source.
b) multi-electrode resistivity survey (2D and 3D) and multi-electrode induced polarization survey (2D IP), in association with the PDGF-10 intelligent cables, electrodes and power source.
c) multi-electrode resistivity survey (2D) when works together with WDZJ-4 Multiple Electrode Converter, power source, electrodes and corresponding cables. This user's manual only gives introduction to general resistivity/IP survey. WDA-1/WDA-1B can be applied in a variety of complex regions and has widely used in metal and non-metal mineral resources prospecting, city geophysical exploration, and railway and bridge inspection; in hydrology and engineering geology to inspect base of dam and flood protection levee for incipient faults. Besides, it contributes to geothermal survey.
WDA-1 Digital DC IP Instrument is different from other instruments:
The WDA-1 digital DC IP meter is different in that it integrates advanced transmitting and receiving functions, is lightweight and flexible, and is capable of working with a variety of instruments.
The WDA-1 digital DC IP instrument is an instrument that integrates the latest electronic technologies such as a full Chinese handheld computer, Bluetooth, 24-bit A/D, and high-power control. Its size and weight are significantly reduced. Its main technical indicators and functions It is ahead of the current similar products at home and abroad. This instrument can better work in areas with various complex conditions and is widely used in metal and non-metal mineral resource exploration, urban geophysical prospecting, railway bridge exploration, etc. In addition, it is also used in hydrological and engineering geological exploration such as searching for groundwater, determining the location of hidden dangers in reservoir dam foundations and flood control embankments, and can even be used in geothermal exploration.
The uniqueness of the WDA-1 digital DC IP instrument lies in its true "one machine with multiple functions". The improved voltage and current range and small signal measurement accuracy make the instrument capable of being used as a rock sample tester and a high-power IP receiver. , conventional resistivity meter, polarization meter, water finder, 2D and 3D high-density electrical meter host and other instruments work. In addition, the instrument also has the characteristics of multiple measurement parameters and wide application. It can measure voltage, current, apparent resistivity, natural potential, apparent polarizability, metal factor, half-life, attenuation, excitation ratio, deviation and voltage. A wide range of parameters, including attenuation, make it a highly flexible and powerful tool.
To sum up, the WDA-1 digital DC IP instrument is different in its lightweight and flexible design, powerful function integration and wide range of application fields, making it an important technological advancement in the field of geological exploration.
