Product Description

Geophysical Resistivity Tool Geo Electrical Prospecting Instrument Resistivity IP Survey Instrument Resistivity IP Meter For Underground Layer Exploration

The Geophysical Resistivity Tool, also known as the Geo Electrical Prospecting Instrument or Resisitivity IP Survey Instrument, is a versatile device used for underground layer exploration. With its applications in mineral exploration, environmental studies, engineering investigations, geological mapping, and archaeology, it contributes significantly to subsurface characterization and resource assessment. The integration of resistivity and IP measurements provides valuable insights for researchers, geologists, and geophysicists, aiding in the understanding of subsurface conditions and facilitating informed decision-making.


Near surface geophysical resistivity meters are an essential tool for earth scientists involved in the study of the subsurface. They are mainly used to measure the electrical resistivity of the earth's subsurface. The resistivity of the subsurface plays a significant role in determining the distribution of groundwater, the location of mineral deposits, and the characteristics of soils and rock formations.

The DC Earth Resistivity Meter is a portable instrument that is relatively easy to use and operate. It has a direct current (DC) source that injects a current into the subsurface. The current is measured by a set of electrodes placed on the ground surface, and the voltage is measured between other electrodes. The instrument then uses Ohm's law to calculate the resistivity of the subsurface.



WDDS-2/2B digital resistivity equipment is a new generation of DC resistivity instrument which is based on a series of advanced electrical equipment for resistivity sounding survey, and adopts 32-bit microcontroller technology and 24-bit A / D technology development.
 
WDDS-2 Geophysical 1D Digital Resistivity VES Method Exploration Meter for Underground Water Detection is the basic resistivity meter only with function of 1D Res Sounding. WDDS-2B designed with a internal high power on the basis of WDDS-2, up to 200V.

Applications:

The main application of the DC Earth Resistivity Meter is in the study of hydrogeology, mineral exploration, and geotechnical engineering. The resistivity measurements provide information about the subsurface's properties, including the presence of groundwater, the location of minerals, and the stability of the ground.

In hydrogeology, the instrument is used to locate the sources of groundwater and to determine the direction of flow. Resistivity measurements can also provide information about the porosity and permeability of the subsurface.

In mineral exploration, the DC Earth Resistivity Meter can be used to locate ore deposits. Ore deposits have a different resistivity from surrounding rocks, which makes them easy to locate. The instrument can also provide preliminary information about the size and shape of the deposit.

In geotechnical engineering, the instrument can be used to determine the stability of the ground and the presence of subsurface voids. Voids have a low resistivity compared to surrounding soils and rock formations. The instrument can also provide information about the properties of the soil and rock, which is essential in designing foundations for buildings, bridges, and other infrastructure.

The DC Earth Resistivity Meter is a powerful tool used in earth sciences research for resistivity measurement. It is portable, easy to use, and can provide valuable information about the subsurface's properties. Although the instrument has some limitations, it is still an essential tool in hydrogeology, mineral exploration, and geotechnical engineering.
