Set of CPT Sounding Tubes (36 mm)

Set of 40 CPT sounding tubes; multiple sets available. These tubes are used to push the electric or mechanical cone into the ground by means of a CPT penetrometer pusher. The tube material is manufactured by one of Europe's leading steel manufacturers according to our own "Gouda-Geo" standards. All tubes are suitable for any pushing force and for any type of CPT(U) test.

The CPT sounding tubes come with the following thread:

QUICK-LOCK (QLK) Double-Entry Rope Thread

By half of the 1990-ies CPT has become more-and-more a highly productive industry. Operators make up to 14 tests of 25 meter per 8-hour shift. Strain-injuries in wrists and elbows are becoming a real issue and the industry asks for a newly designed thread. This resulted in the Quick-Lock thread.

The main advantages are the number of turns required to lock / unlock (only 2.5 turns), the improved strength of the thread (over 40% stronger than the STANDARD thread) and the relative ease to clean it.
