A&D SJ-20KHS is a 20 kg × 10 g portable bench scale designed for straightforward weighing in food preparation, produce handling, packaging, receiving and mobile inspection. It combines a compact 230 × 190 mm SUS304 stainless pan with approximately one-second stabilization, a large 25 mm LCD, four-D-cell battery operation and an optional AC adapter.

Core SJ-20KHS specifications
The current A&D SJ-HS specification lists 20 kg capacity and 10 g readability. The scale supports g, oz, lb and lb-oz units, has stable, zero, net and battery-status indicators, includes zero tracking and auto power-off, and uses a low-profile housing with two side handles. Current manufacturer information gives approximately 2,000 hours of alkaline-battery operation—substantially longer than figures found in some older catalog material.
Who should choose the SJ-20KHS?
The model is a strong fit when loads exceed the range of 5 kg or 12 kg compact scales but a full industrial floor platform would be unnecessarily large. Typical users include bakeries weighing dough batches, produce operations checking boxes or bags, kitchens handling bulk ingredients, packers verifying finished goods and receiving teams checking components or supplies. Its compact footprint is useful on crowded worktables, but the load must sit fully and freely on the pan without touching the bench, display housing or nearby equipment.
Food and sanitation considerations
The SUS304 pan and NSF-compliant family design support food-related work. The SJ-20KHS is not marketed as a sealed washdown scale, so remove the pan for cleaning, use a damp compatible cloth on the housing and keep liquid out of the battery compartment and controls. Operations needing routine water-jet cleaning should select an appropriately rated washdown model rather than treating stainless pan material as an enclosure rating.
External calibration and routine verification
SJ-20KHS uses external calibration. Calibration should follow the manufacturer procedure with a suitable reference mass after the scale is level, stable and acclimated. Routine users should also verify zero, repeatability and a known working-range load before important batches. A successful calibration routine does not correct a container touching the housing, an unstable table, a low battery or product movement.
Portable power and workstation planning
Four D batteries make the scale practical for carts, markets, temporary production lines and receiving areas without a nearby outlet. Use matched batteries, replace the full set together and remove them before long storage. After moving the scale, place it on a rigid surface and verify it with a known weight before relying on a tight tolerance. The optional AC adapter is better for a fixed station that operates continuously.
SJ-20KHS versus nearby SJ-HS models
SJ-12KHS provides 12 kg × 5 g for users who need finer readability and less capacity. SJ-30KHS extends capacity to 30 kg but reads in 20 g increments. Choose based on the heaviest container-plus-product load and the smallest meaningful process tolerance. Buying excessive capacity can sacrifice useful resolution, while choosing too little capacity risks overload and forces awkward split weighing.
Legal-for-trade use
Do not infer legal-for-trade approval from the SJ family name or from the presence of pound units. When weight determines a customer price or another regulated transaction, confirm the exact approved model, configuration, certificate and local placement-in-service requirements before purchase. The SJ-20KHS is commonly selected for internal process weighing and portion control.
Frequently asked questions
What are the capacity and readability? 20 kg × 10 g. How large is the pan? 230 × 190 mm. Is the pan stainless? Yes, SUS304. How fast does it stabilize? Approximately one second under suitable conditions. What batteries does it use? Four D cells. What is the current alkaline-battery estimate? Approximately 2,000 hours. Is calibration internal? No, external. Does it have RS-232C or counting? Those functions are not listed for the SJ-HS family. Is it washdown rated? The SJ-HS page does not identify an IP washdown rating. Is the product image exact? It is clearly labeled representative SJ-HS family artwork from the MNM catalog.
