The first essential step in grain grading is to obtain a correct and representative sample. Cars, trucks, wagons or barge loads should be sampled with a double tube probe in five or more places. Also used for plastics, Seedburo probes are made to conform to USDA specifications.
They are constructed from extra heavy gauge tubing for durable, time-tested sampling. All probes on this page have an outside diameter of 1-3/8", are of double-tube construction and have a heavy bronze point (unless otherwise stated). Openings are 3-3/8" L x 7/8" W.
KEYSTONE CARBON PROBE: This probe has an auger vane to assist with sampling 'packed material' and aids in drilling down into the sample. Auger extends about 1/4 of the way up the probe. Diameter of the auger section is 2-5/8".
PARTITIONED GRAIN PROBE WITH WOODEN HANDLE: Partitioned grain probes are used by the U.S. Department of Agriculture and by all grain inspectors. There is a separate compartment for each individual opening. Samples from these probes can be emptied on a grain sampling canvas.
OPEN-HANDLED GRAIN PROBE: Open-ended probes without partitions are more convenient to empty and are widely used by the grain elevator operators for obtaining samples from truck loads. After sample is obtained, probe is held upright and sample is dumped from the handle.
