The QL40-FTC, QL40-FTC-I, and 40FTC probes provide borehole temperature and fluid conductivity measurements. The standard temperature log, based on a thermister, is designed to provide a measure of the ambient geothermal gradient and is helpful to detect anomalies caused by events such as fluid flow into the borehole. The borehole fluid conductivity is directly proportional to the concentration of dissolved minerals. It is generally used in hydrogeology to determine the concentration of dissolved ions in the aquifers and to locate the fluid flows occurring in the borehole, especially if some time has passed and the temperature features have dissipated. It is important to differentiate between fluid inflow anomalies and formation conductivity anomalies identified on the temperature logs.

The QL40-OCEAN Idronaut Ocean Seven 303 probe combines a multi-parameter sensing unit manufactured by Idronaut srl, Brugherio, ITALY. This water quality probe is specifically designed for groundwater and environmental investigations. It uses reliable, accurate and drift-free high quality sensors and records a continuous profile of the borehole fluid properties. In the standard configuration, the QL40-OCEAN probe is equipped with six sensors to measure: Pressure, Temperature, Conductivity, Dissolved Oxygen, pH and Oxidation reduction (REDOX) potential.

The QL40-SFM Spinner Flowmeter probe measures impeller rotation caused by groundwater flow in the borehole. It uses a magnetically coupled pick-up which drives a low friction, high resolution encoder located inside the lower pressure housing. The encoder produces 256 pulses per shaft rotation. It has quadrature sensing electronics that instantaneously detect flow direction changes. The QL40-SFM flowmeter tool is stackable within the Quick Link (QL) product line or it can be run as a standalone tool.
