300m Geophysical Equipment Borehole Water Well Log Tool 1% (Scale)
Apparent Resistivity Measurement Accuracy
Product Description
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.
