Specification :

High-density risitivity is a risistivity exploring method that integrated with electrical profiling and electrical sounding adopts high-density pointing to measure two-dimension geoelectric cross section
It supplies large data and information also is of high-precision observation high – speed and deeply detecting, which is wildly applied in geoengneering, hydrology exploring
RIS-2D distributed high-precision risistivity instrument, a new high-precision resistivity “ Four electrode electrical system� successfully studied by our company. It is setted with 60 exchange swiches, increased its fouction and reliability.
