The RCQ-1 Geophysical Coring Drill is a reliable geophysical coring instrument for measuring apparent resistivity and spontaneous potential in boreholes. It consists of a surface instrument, a Kevlar cable, an electric winch, and a probe with downhole electrodes, ensuring accurate and stable data acquisition. The system utilizes an adaptive power supply scheme, delivering an AC square wave to the formation while simultaneously measuring current and voltage. This enables accurate resistivity recording over a wide measurement range.
The RCQ-1 is lightweight and easy to use, connecting directly to a PC for real-time data recording, transmission, and plotting. It is widely used in applications requiring reliable borehole resistivity data, such as groundwater exploration, mineral exploration, engineering geology, and geotechnical investigations.
