QL40-CAL – 3-Arm Caliper

Description The QL40-CAL Caliper probe records a single continuous borehole diameter log by means of three mechanically coupled arms in contact with the borehole wall. The 3 arm caliper measurement is a useful first log to determine the borehole condition before...

QL40-OBI-2G – Optical Televiewer

The New 2nd Generation Optical Televiewer is Here!   Description The QL40-OBI-2G and OBI40GR-2G are the new generation of Optical Borehole Imagers. The new televiewer comprises a completely redesigned optical assembly with new electronics. It implements a high...

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...
