STRUCTURE AND USE
The mechanical probe consists of double tubes. An outer and smaller inner tube. Each tube has intervals for sampling. By turning the handle, the gaps are provided to coincide with the outer tube.
Make sure the gaps are closed before sticking to the material. It can be stuck to a depth of 3 meters. Turn the ergonomic handle counterclockwise until it stops. The gaps will open spirally from bottom to top. In this way, 100% representative sample is guaranteed.
Turn the handle clockwise, cover the gaps, remove the probe from the material stack and empty the entire sample from the gap of the grips.
The probe does not require special maintenance. Do not twist or shake while in the material. A probe will live with you for a lifetime.
