Geoprobe® brand Dual Tube Sampling Systems are efficient methods of collecting continuous soil cores with the added benefit of a cased hole. Our line of Dual Tube Soil Sampling Systems include: DT22, DT325, DT35, DT37, DT45, and DT60.
The DT60 sampling system is the largest dual tube system from Geoprobe®. It boasts two innovative features that have patents applied for. It utilizes 6 in. OD percussion driven casing and collects a 4 in. diameter soil sample. Unlike most other sampling systems, the DT60 uses a patent pending split sheath which gives the user the option of not using a liner.
