Access Tubes and Augers
The penetration depth of the measurement field of the 44mm TRIME tube-access-probe is up to
150mm into the soil. The measurement sensitivity is the highest near the access tube and de-
creases exponentially into the medium. Therefore the insertion method of the access tube is
very important.
Pre-boring of bore holes with standard augers destroy the soil texture, because it is difficult to
come to a good and close contact of the access tube inside the soil. With the described auger
equipment it is possible to set the access tubes directly into homogenous soils without pre-
boring. In very stony soils it is not possible to use this method. Therefore it could be possible to
use an Edelman-Auger for pre-boring and closing the air gaps with mud. Changes in soil struc-
