WDDS-2 digital resistivity meters for display:
Resistivity meters for features:
WDDS-2 resistivity meters for ground water exploration instrument is a new generation intelligence multi-electrode resistivity instrument. It can automatically measure and memorize voltage, current, apparent resistivity, and SP parameter.
It is widely used in the following fields:
1. Hydrological and engineering survey, such as resistivity meters for ground water exploration;
2. Dam base evaluation and flood control dam incipient fault and so on.
3. It also can be applied in engineering geological prospecting, such as metal-nonmetal mineral resources exploration, urban exploration, railway and bridge, even in the geothermal exploration.
