Resistivity Meter Tomography Equipment for Water and Mineral Detection Underground Water Detector Geophysical Electrical Resistivity Tomography
1. 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.
2. 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.
3. Accessories made by our factory with 60-channel or 120-channel multiplex electrode switch, also can be used for multi-electrode resistivity survey system.
FEATURES:
· 1) Small volume and lightweight: The emitting and reception are combined in the same case. It is able to take apparent resistivity
Measurement and induced polarization measurement simultaneously.
· 2) Many measurable parameters: Primary field potential Vp, Self-potential voltage (namely Vsp), Supply current I, Apparent resistivity Ro (namely Ps), Apparent polarizabilityM1~7 (namely S1~7), Half-life time TH, Degree of damping (D), Deviation (R), Synthesis excited electron parameter Zp.
· 3) Convenient and flexible operation: Adopting automatic digital measuring, the instrument can automatically compensate for self-potential, drift and electrode polarization. With the large LCD screen, 9 patterns of poles distribution can be displayed. During operation, the parameters are inputted through key panel. After one point is measured, the curves of apparent resistivity, apparent polarizability and half-life time are displayed directly.
· 4)Convenient for data interpretation: The instrument can store the measured results up to 1200 points. Through the serial port RS-232, the measured data can be transmitted to the computer. With the help of related software, several methods can thenbe used for digital interpretation.
· 5)The instrument adopts a large screen and a multi-layer touch panel with thin-film sealing. And self-protection of over-voltage and heavy current in power part make the instrument applicable for various field environments.
