The resistivity/conductivity cone penetration test (RCPTu) combines the downhole measurement of soil resistivity/conductivity and the logging capabilities of the cone penetration test (CPTu or SCPTu). The RCPTu provides a rapid, reliable, and economic means of determining soil properties in addition to providing relative measurements of electrical resistivity/conductivity.
Features
Bulk soil / pore water electrical resistivity/conductivity measurements with all CPTu / SCPTu advantages
Dipole or ring electrode configurations
Polynomial calibration over a wide range of resistivities/conductivities (salt water - dry soil)
Soil resistivity/conductivity is a function of soil type, void ratio, saturation, and pore water chemistry
Specifications
Resistivity/Conductivity module has 15 cm2 cross-sectional area
Rapidly connects to all ConeTec 15 cm2 cones
Resistivity/Conductivity measurement located 0.80 m behind CPTu tip
Can be deployed with or without the CPTu / SCPTu probe attached
ADvantages
Determine soil / water resistivity/conductivity while collecting all other CPTu / SCPTu parameters
