300m Geophysical Equipment Borehole Water Well Log Tool Apparent Resistivity Measuring Logging System
Product Description
The RCQ-1 Borehole Logging Equipment is a reliable geophysical logging tool designed for measuring apparent resistivity and natural potential in boreholes. It consists of a surface instrument, Kevlar cable, electric winch, and downhole electrode probe, ensuring accurate and stable data collection. With an adaptive power supply scheme, the system delivers AC square waves to the formation while measuring current and voltage simultaneously. This enables precise resistivity logging across a wide measurement range.
Lightweight and easy to operate, the RCQ-1 connects directly to a PC for real-time data recording, transmission, and mapping. It is widely used in groundwater exploration, mineral surveys, engineering geology, and geotechnical investigations where reliable borehole resistivity data is required.
