Application:  

1. Water resources, metal and nonmetal mineral resources detection

2. City geophysical exploration, railway and bridge inspection 

3. Hydrology and engineering geology as inspecting dam base and flood protection levee for incipient faults 

4. Geothermal prospecting

 

Function:   

1. 1D resistivity sounding 

2. 1D induced polarization sounding

3. 2D Electrical resistance tomographic

 

Main Features:

1. Transmitting unit and receiving unit are of all-in-one design, portable and lightweight.

2. Super high-power, high anti-interference performance and precision: up to 6600w (1100v×6A) power, 48Vp-p voltage range ensures to get a good result in a area with high resistance.

3. Automatically achieving compensation of self-potential, drift and electrode polarization, up to ±10V.

4. Receiving unit support transient over-voltage protection, transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection.

5. For general resistivity and IP survey function, 9 types of electrode arrays are available. Electrode distance (namely “Program”) can be inputted or called. Geometric factor K can also be generated automatically or calculated manually. 

   

For multielectrode 2D resistivity imaging, up to 18 electrode arrays are available. It could scanning measure according to fixed section (including AMNB, ABMN, AMBN, AMN, MNB, A-MN

B, Sp M, Sp MN, charge M, charge MN) or continuous rolling scanning measure according to variable section (including A-M, A-MN, AB-M, AB-MN, MN-B, A-MN rectangle).

1. Program: the program can memorize 100 groups of electrode distances, avoiding repetitive input. Or you just input a program Id and step to call the corresponding electrode distances.

2. Earth resistance inspection: ground condition can be inspected at any time.

3. Mass data storage: Up to 1GB capacity (extended) enable store 5,000,000 groups measuring data (including current, voltage, SP, Ro, Ms, metal factor, TH, R, J).

4. All parameter and data are under power-failure protection; and thus data will not be lost even thought the system shuts down accidentally.

5.  USB port enables it to transfer data to computer.
