DUK-2A high density electrical measurement system

Brief introduction:

This system is widely applied in the levee hidden trouble detection (such as a nest of river levee, rat holes and weak intercalation and crack of high resolution exploration) coal mine goaf, Custer the karst caves in the area, such as landslides and other geological disasters can be exploration.

Workshop foundation, highways, Bridges, railways, civil air defense engineering hydrology, engineering, environment of high resolution geological exploration.

Metal and non-metallic mineral resources exploration and geothermal exploration. DZD - 6 a multifunctional dc method for measurement and control host, match with my factory production of new or 120-2 type a 60 tao multi-channel electrode converter and big wire and cable, electrode and related accessory constitute the high density resistivity method measuring system.

Features:

1. One can: instrument has long wires excited all, 2 d high-density resistivity meter, two-dimensional high-density activated all and short wire transmitter power four functions.
2. Easy to operate: the equipment adopts full digital automatic measurement, for sp, drift and electrode polarization automatic compensation. Using large screen LCD display Chinese characters, in high density measurement mode can be directly display more than fourteen wiring work mode; When DZD - 6 a stand-alone mode can directly display nine electrode arrangement; At the same time on the job can be real-time display curve, etc.
3. Large storage: in high density mode, the instrument measuring data of 120000 points may be stored; When DZD - 6 a stand-alone mode, can the 4800 data for storage, the site of each measuring point number 22, is equipped with RS - 232 serial interface, through the corresponding software can be directly stored data into the computer, for a variety of methods of digital explanation.
