QL40-FTC
from Mt Sopris
The QL40-FTC and QL40-FTC-C Fluid Temperature Conductivity probes provide precise borehole temperature and fluid conductivity measurements. The FTC-C is a bottom sub, while the FTC is an inline sub, and both can be run stand-alone or stacked with other QL tools for custom configurations.
The QL40-FTC and QL40-FTC-C probes can be calibrated in µS/cm or mS/m for conductivity and in °F or °C for temperature. Commonly stacked probes include the QL40-GR (Natural Gamma), QL40-RES (Multi-Point Resistivity), and QL40-CAL (3-Arm Caliper). Due to its design, the QL40-FTC probe is best placed at the bottom of a stack for improved measurement accuracy.
Basic water quality logs with these probes are invaluable in groundwater studies, geothermal gradient logging, salt-water intrusion research, and a variety of environmental projects.
