Needing a larger sample? Want productive, efficient soil sampling methods in the field? Tired of handling larger casing with conventional sonic methods? Geoprobe® has developed the SDT60 sampling system… A Dual Tube System that advances our 6 in. casing and collects samples without the overcasing conventional method.
SDT60 Soil Sampling Methods
The core barrel is advanced simultaneously with the outer 6 in. casing. Our 2.25 in. inner rods remove the core barrel and the 4.3 in. diameter sample is collected into core bags. By advancing the casing and inner rod string together, you achieve an increase in productivity and minimize the handling of casing.
Faster trip in and trip out time compared to 4x6 soil sampling methods
Outer 6 in. casing and inner sampler are advanced simultaneously
Continuously collect 4.3 in. diameter soil cores
True 6 in. diameter borehole
Set 2 in. monitoring well through 6 in. casing
Core catcher helps provide retention of soil samples
