Automatic Geophysical equipment Deep Ground Water Detector
Main Applications about ground water detector:
By utilizing relevant parameters of apparent resistivity and induced polarization
method, the instrument is widely used in many aspects including metal and non-metal
mineral resources exploration, energy exploration, city geophysical exploration,
railway and bridge engineering exploration, etc.
Search for groundwater, solve the human and animal drinking water issue as well as
industrial and agricultural water issue. Determine the hidden safety risk location
in reservoir dam foundation and flood-control dyke, find faultage zone and collapse
column, landslides, coal mining goaf, search for geothermal and other hydrological,
engineering geological exploration.
Accessories made by our factory with 60-channel or 120-channel multiplex electrode
switch, also can be used for multi-electrode resistivity survey system.
Main features about ground water detector:
1,Small-sized, Light in weight: The instrument integrates receiver and transmitter
together in the same cabinet, which can be used for measurement via apparent
resistivity method and induced polarization method.
2,Various Measurement Parameters: Instrument can be applied in direct measurement and
indication of primary potential Vp, spontaneous potential Vsp,power supply current I,
apparent resistivity Ro, apparent polarizability Ms, half-decay time Th,degree of
decay D,integrated IP parameters Zp, and degree of deviation R.
