Features
Underground Water Detection Ground Water Detector Geophysical Equipment Resistivity Imaging, Electrical Resistivity Sounding ,Resistivity Meter
Small volume and lightweight: The transmitter and receiver are combined together. It is able
To take apparent resistivity measurement and induced polarization measurement
Simultaneously.
Many measurable parameters: Primary field potential Vp, self-potential voltage Vsp, supply
Current I, apparent resistivity Ro, apparent polarizability Ms, half-life time Th, attenuation D
And deviation R, and induced polarization parameter Zp.
Convenient operation: Automatic digital measuring. Automatically compensation for self-
Potential, drift and electrode polarization. With the large LCD screen, 9 patterns of poles
Distribution can be displayed. During the operation, the parameters are inputted through
The key panel. After the point is measured, the curves of apparent resistivity Ro, apparent
Polarizability M and half-life time are displayed directly.
Data Storage: It can store 4800 points' measurements and 22 data for each point.
Data Transmission: RS-232 channel available to dump data from instrument to PC.
Self-protection of over-voltage and heavy-current.
