The Dual-Tubed Probe has seamless construction with durable points. Inner tube is rotated to open/close sampling holes. The probe with partitions between holes have closed-end handle, and pockets are emptied individually. Those without partitions have open-ended handle for convenience of emptying total sample. Partition type is USDA approved for grain sampling.
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.
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.
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.
