We manufacture window samplers from precision tubes. The head and cutting shoe are made of heat-treated alloy steel. A sampling window is integrated into the tube for every 0.5 m of length. The cutting shoes are available in either fixed (welded) or screw-on designs.
Our window sampling tubes with M20 threaded connecting pin are compatible with 32 mm sounding rods used for DPH dynamic probing and are recommended when driven soil sampling is performed using a drop hammer impact unit.
This threaded connection is unsuitable for gasoline or electric hammers (Wacker, Makita, Bosch) operating at significantly higher impact frequencies.
Upon request, the window sampling tubes are available with a tough M20 stainless steel threaded connecting pin.
