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-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-SGR-2G – Spectral Gamma

Description The QL40-SGR-2G is a new generation of borehole logging Spectral Gamma Tool. This new logging probe consists of a completely redesigned and ruggedized mechanical assembly, electronics and gamma module. It implements also the latest telemetry developments...

QL40-ELOG – Electrical Resistivity

Description The QL40-ELOG digital probe measures 8, 16, 32 and 64 inch normal resistivity, single point resistance (SPR) and spontaneous potential (SP) simultaneously. Users can log resistivity profiles with different depths of investigation and gain information about...

QL40-GR – Natural Gamma

Description The QL40-GR probe measures the amount of gamma radiation occurring naturally within the formations crossed by a borehole. Gamma rays are produced mainly by isotopes of potassium, thorium, and uranium. The gamma log is widely used in the groundwater and...

40GRP – Gamma + Resistivity

Description The 40GRP-1000 combination probe is ideal for slimline, one-pass, hydrogeological studies, lithology work, uranium exploration, and general borehole formation data. The totally digital probe combination measures 16, 64 inch (0.4, 1.6 meter) normal...
