HIGH DENSITY
ELECTRICAL MEASUREMENT SYSTEM
ELECTRICAL MEASUREMENT SYSTEM
It is widely used in the detection of hidden dangers in embankments (such as high-resolution
detection of anthills, rat holes, weak interlayers and cracks in river embankments); Exploration of geological hazards such as
detection of anthills, rat holes, weak interlayers and cracks in river embankments); Exploration of geological hazards such as
coal mine goafs, karst caves and landslides in the Karst area.
High-resolution engineering geological exploration of plant foundations, highways, bridges,
railways, civil air defense projects, hydrological projects, etc. Exploration of metallic and
non-metallic mineral resources and geothermal exploration.

Specification
System features
The system uses EDFD-12 microconverter to connect 12 centralized cables, which
overcomes the shortcomings of many distributed cable circuit nodes, high failure rate, and the
difficulty of on-site construction in centralized high-density system. It can be rolled in units of 12
integer multiples of electrodes to achieve long profile measurements. Android terminal remote
control, convenient and flexible, simple operation, rich display information, large data storage. Up
to 19 pole running methods, and can also be pre-ordered according to user needs
