Van der Horst Probennehmer Set

By hammering the sampler into the material (by hammer with nylon heads or slide hammer) the core is filled. When the sample enters the tube, the water or air trapped above the sample can escape through a non-return valve. The sample can be retrieved by using the support and lever beam with rope catcher. This set includes a hydraulic sample extruder, for effortlessly extraction of the sample.

Samples can be taken from bore holes, casing tubes (minimum diameter 75 millimetres) or in the beds of canals, lakes, etc. This sampler set is suitable for hammering.
