2015 Hot!!! Hydrogeology Instrument & High Precision Geophysical Equipment

Hydrogeology Geophysical Equipment

Main application:

1. Metal ore, non-metal ore and underground water general survey.
2. City prospecting, engineering exploration like railway &bridge, resistivity imaging survey of archeological mining and geological structural mapping etc.
3. Hidden faults in dikes detect, such as high resolution prospecting of ants-nest &rat hole of river levees, weak intercalation and fracture.
4. 4. Geological exploration in hydrology, engineering, environment and high  resolution resistivity method engineering.

     5. Detect of coal goaf, civil air defense works and cavities in karst area. Also geological disaster of factory foundation, highway, bridge, railway and landslide etc.

Main features:

1.High resolution and high efficiency electrical prospecting: 
The system consists of two parts: DZD-6A multi-function DC resisitivity meter and the multiplexor. It is used to explore matching with the high-new technology such as CT and auto conversion measure and supply of electrodes based on the theory of regular resisitivity methods.   

2.Time domain DC resisitivity method and IP method:  
DZD-6A multi-function DC resistivity meter can be solely employed to perform resisitivity and IP survey under conventional modes. There is many parameters in this mode: spontaneous potential (Vsp), primary field potential (Vp), supply current (I), apparent resisitivity RO(ps), apparent polarizablility (M1-6), half-life time (Th), degree of damping (D), synthetic excited electron parameter (Zp) and degree of deviation (R).

3.More flexible and convenient operation method:  
It can auto-compensate self-potential, drifting and electrodes polarizing by employing full digital auto-measurement. Results are displayed on large LCD screen which can list more than 14 kinds of array modes under resistivity imaging survey. In DZD-6A’s single mode it can display 9 electrode arrays and measured curves timely as well.   

4.Convenient data explanation:  
a. It can store data up to 120000 points in resistivity imaging survey mode.  
b. It stores data of 4800 points in DZD-6A single mode, and each point includes 22 figures. Data can be directly transmitted to a PC for digital explanation by corresponding software.
