Multi-Channel Switch 120 Automated 2D Imaging System for Underground Condition Exploration
WDJD-4 Multi-function Digital DC Resistivity/IP Meter is our new generation model with 32 single-chip and 24 bit A/D technology on the basis of years of experience of design and manufacture, which could carry on Res and IP survey at the same time. It features multiple functions, high accuracy, fast speed, high reliability and excellent expandability. Measured data of WDJD-4 can be processed by other multi-electrode resistivity software, which makes the interpretation more convenient.
The single WDJD-4 can conduct general electrical resistivity/IP survey with twist pair wire, iron electrodes and power source. If WDJD-4 is used together with WDZJ-4 multiplex electrode switcher multi-electrode cable, electrodes and power source, it can conduct not only general electrical resistivity/IP survey but also multi-electrode 2D Resistivity imaging.
