Light Weight ≤4.2Kg Geophysical Resistivity Meter with Methodological Flexibility and Research-Grade Data Transparency

The WDDS-3C Digital Resistivity Meter serves as a foundational research tool for academic institutions, providing faculty, researchers, and graduate students with a versatile, publication-grade platform for investigating critical zone processes. Designed as a transparent, configurable scientific instrument, it supports methodological innovation and pedagogically rich field training while generating novel datasets for hydrology, geomorphology, soil science, and biogeochemistry research.

This system supports standard electrode arrays (Wenner, Schlumberger, Dipole-Dipole) while enabling completely custom, user-defined array geometries for novel survey methodologies. Raw data—including voltages, currents, and geometries—are exported in open ASCII and EDI formats, allowing researchers to apply advanced inversion codes, statistical analyses, and petrophysical transforms for comprehensive data interpretation.

The WDDS-3C serves as a cornerstone for interdisciplinary field courses, providing hands-on experience with industry-standard technology. It supports undergraduate capstone projects and Masters theses while producing data of sufficient quality for peer-reviewed publication. The instrument's durability ensures it can serve multiple student cohorts across demanding field camps, elevating pedagogical stature and attracting high-caliber graduate students.
