QL40-SFM – Spinner Flowmeter

Description 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...

QL40-FWS – Full Waveform Sonic

Description The QL40-FWS Full Waveform Sonic tool is used extensively in the groundwater, mining, and geotechnical industries. Sonic logs are widely employed, often in combination with other logs, to provide porosity, permeability, and geo-mechanical properties. This...

QL40-IND – Dual Induction

Description The QL40-IND Dual Focused Induction probe provides two simultaneous conductivity logs, corresponding to “Medium” and “Deep” radii of investigation into the borehole. The two depths of penetration are useful in porous, permeable formations where...

QL40-HM – Magnetic Susceptibility

Description The QL40-HM borehole magnetic susceptibility tool is typically used in mining, geotechnical, and lithology applications. All electronic circuitry resides in a high strength non-magnetic enclosure. The operating frequency is chosen to be sufficiently low to...
