ZHANGMIN Grain Probe Sampler, Stainless Steel Powder Sampler with Three Zone, Double Tube Rotary Sampling Tool for Grains, Granules & Powder Sampling(1m)

• Robust Stainless Steel Construction: This grain probe sampler is crafted from premium stainless steel for long-term industrial use. This solid stainless steel powder sampler maintains a clean surface that will not cross samples of grains, feed, or industrial powders. The one-piece seamless design ensures structural integrity even under repeated heavy-duty bag insertion and material extraction
• Precision Double Tube Rotary Mechanism: The double tube rotary design of this powder sampler enables smooth stratified sampling with a simple handle turn. Insert the grain sampling probe into the bulk material, rotate the handle to open multiple sampling slots, collect materials from different depths simultaneously, then reverse the rotation to seal. This one-insertion multi-depth mechanism improves sampling efficiency by 70% compared to single-tube alternatives, delivering representative samples in half the time
• Multi Slot Design for Representative Sampling: Equipped with three interlinked sampling slots, this stainless steel grain probe sampler captures cross-sectional samples from the top, middle, and bottom layers of any bulk container or grain silo in a single insertion. The slot configuration delivers true representative sampling required for quality control of corn, wheat, rice, fertilizer pellets, plastic granules, and powdered industrial materials
• Versatile Material Compatibility: This bulk material sampling tool works effectively across a wide range of dry commodities. Insert the grain sample probe into bagged or bulk-stored wheat for flour mill quality checks, sample feed pellets at livestock facilities, extract fertilizer granules for chemical analysis, or collect powdered metal particles for industrial testing
• Portable Lab and Field Sampling Tool: Designed with an arrow-shaped pointed tip for effortless penetration into packed grain bags and bulk material piles, this powder sampler operates without electricity or compressed air, making it ideal for remote warehouses, outdoor grain silos, and on-site factory inspections. The sampler disassembles completely for easy cleaning between different product batches, ensuring no cross when moving from one material type to another

The Grain Probe Sampler is a stainless steel double tube rotary sampling tool designed for quality control professionals who need accurate samples from bulk dry materials including grain, feed, powder, and industrial granules. This stainless steel powder sampler replaces inefficient scoop-and-bag methods with a precision mechanical mechanism that captures true cross-sectional samples in a single insertion. The entire assembly is crafted from stainless steel, providing the strength needed for repeated bag penetration and the damage resistance required for long-term use in agricultural, food processing, and industrial facilities. How the Rotary Grain Probe Sampler Works: This powder sampler operates on a simple double tube rotary mechanism. Insert the closed probe into the bulk material bag, grain bin, or industrial container to the desired depth. Turn the handle to rotate the inner tube relative to the outer tube, aligning the sampling slots so material flows into the collection chambers. After the slots fill, reverse the handle rotation to seal the probe. Withdraw the grain sampling probe from the material. Turn the handle again to reopen the slots and discharge the sample into your collection container or testing bag. This one-insertion multi-layer capture method delivers representative samples faster and more consistently than probing and scooping at multiple depths. Product Specifications: Available diameter and length configurations for this stainless steel grain probe sampler include : Match the probe diameter to your material particle size to ensure smooth material flow without clogging. Key Features Detailed: Stainless Steel Material: The probe body, inner tube, handle, and pointed tip are all manufactured from stainless steel. Double Tube Rotary Mechanism: This rotary grain probe uses an inner collection tube that rotates within the outer slotted tube. This double-wall design allows the sampling slots to remain sealed during insertion and withdrawal, then open precisely at the target depth for material collection. The smooth rotation action requires minimal hand force even when probing compressed grain in full silos. Multi Slot Cross Section Sampling: The sampling section contains 3 or 4 interconnected slots positioned at different heights along the probe. When the double tube mechanism is opened, material enters all slots simultaneously, capturing a vertical cross-section of the storage container. This design addresses the common limitation of point samplers that only collect material from a single depth, providing true representative sampling required for accurate moisture testing, foreign material inspection, and quality grading. Sharp Pointed Tip for Easy Bag Penetration: The lower end of this grain sampling probe features an arrow-shaped pointed tip that easily pierces woven poly bags, paper sacks, and bulk bin liners without tearing or shredding packaging material. The tapered tip geometry also helps guide the probe through settled grain and compressed powders, reducing the insertion force required compared to flat-ended probes. Product Specifications: Product Name: Stainless Steel Grain Probe Sampler / Powder Sampler Material: Stainless steel (entire tool) Design: Double tube Operation: Rotary handle (90° open/close) Tip Type: Sharp arrow head Available Diameters: 32mm Available Lengths: 1m (3.3ft), 1.5m(4.9ft) and 2m (6.6ft) Package Contents: 1 x Stainless Steel Grain Probe Sampler (diameter and length as selected) The sampler is shipped fully assembled.
