Inventor and manufacturer of the all-electric core sampler grain truck probe and rail car probe.

Our all-electric grain probe for trucks or rail cars is a closed, forced air system allowing no vacuum in the load. Down pressure of the probe forces a core of grain into the inner chamber of the sampler return tube.
The probe samples high moisture grain or any flowable material. It consistently provides an exact sample with no chance for excess foreign material. The core sampler meets all state & federal regulations and is Type Approved for FGIS Official Sampling.
