ZHANGMIN Grain Probe Sampler, Stainless Steel Powder Probe Tube, Rotate Double Tube Sampling Tool for Powder, Grains and Fertilizer Sampling(D-38mm x L-1m)

• Premium Stainless Steel Powder Sampler: This grain probe sampler is manufactured from stainless steel, a material chosen specifically for its non-reactive surface and long service life in agricultural and industrial environments. The smooth internal bore prevents material buildup and facilitates complete sample discharge. Each stainless steel powder sampler undergoes quality inspection to ensure slot alignment and handle rotation smoothness before packaging
• Simple Three Step Operation for Quick Sampling: Use this rotary grain probe with a straightforward three-step process—insert the closed probe into the material to the desired depth, turn the handle 90 degrees to open the sampling slots and allow material to flow into the collection chambers, then turn back to seal before withdrawal. This double tube sampler design eliminates the need for separate scoops or transfer tools, streamlining the entire grain sampling workflow from penetration to sample retrieval
• Interlinked Slot Design Ensures True Cross Section Sampling: The grain sampling probe features three slots that are interconnected along the central tube. This configuration ensures that once the double tube rotary mechanism is opened, material flows through all three openings simultaneously, capturing a vertical cross-section rather than just surface material or point samples. For silos containing corn or wheat, this layered approach delivers lab-ready samples that accurately reflect the condition of the entire storage unit
• Four Diameter Options for Different Particle Sizes: This stainless steel powder sampler is available in 19mm, 25mm, 32mm, and 38mm diameters with 1m or 1.5m length options for each size. Use the 19mm probe for fine powders; the 25mm version for wheat sampling; the 32mm model for rice and medium granules; and the 38mm probe for corn, peanuts, and large particle fertilizer. Match probe diameter to material particle size to prevent bridging or blockages during sampling
• Easy Clean Design for Multi Product Facilities: After completing grain sample collection, clean this powder sampler by fully opening the slots and flushing with rinsing with appropriate cleaning solution. The stainless steel surface resists staining and does not absorb odors or residues, allowing the same probe to be used sequentially for feed, then powder, then industrial granules without sample carryover. Always dry thoroughly before the next use to prevent material adhesion inside the barrel

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 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: 19mm, 25mm, 32mm, 38mm Available Lengths: 1m (3.3ft) and 1.5m (4.9ft) Package Contents: 1 x Stainless Steel Grain Probe Sampler (diameter and length as selected) The sampler is shipped fully assembled.
