duk-2a underground water detecting 200m depth, water detection meters

タイトルまたは説明

Specifications

it is go through the resistivity and show the 2Dor 3D imaging for help the water and metal detecting

it is Widely used for high-resolution research, tomography and monitoring applications.

 Coal mining gobs, caves of Custer area, geological disasters survey like landslides other geological disasters.

 High resolution engineering geological exploration like factory foundations, highways, bridges, railways, civil engineering, hydrology, engineering, environmental.

 For landslides and other geological disaster exploration.

 Metal and non-metallic mineral resources exploration and geothermal exploration

 

Main Features.

 

 Assembly data acquisition devices and multiplexer together in the same case,which not only reduce the volume but also decrease the weight, thus avoid errors caused by operating the devices separately and due to inconformity of switch parameter settings.

 Maintain all functions ofDUK2A  MultiElectrodes Resistivity Survey System and conventional electrical method.  Add high and low current transform taps, add high and low  impedance transformation tap, and improve the acquisition capability of weak signals.

 Add storage and output functions for compensation SP voltage value.

 Adopt **-bit A/D and **-bit D/A, thus improve the discernibility for measurement of collected data.

 Add the function for automatically detect grounding resistance before each measurement; give directions for the points exceed the grounding resistance value, for automatically proceeding with further measurement if required; the value at such point can be replaced with a fixed symbol to facilitate the elimination of this point while processing the information and data.

 Greatly enhance the repeatability of measured data.
