A&D EK-6100i vs EK-6000i vs EK-6100J is a three-way choice between finer internal process resolution, standard data connectivity and legal-for-trade approval. EK-6100i is 6,000 g × 0.1 g, non-NTEP, with functional standard RS-232C and underhook support. EK-6000i is 6,000 g × 1 g and A&D U.S. explicitly lists it as NTEP Class III, also with standard RS-232C and underhook support. MNM describes the separate EK-6100J as legal for trade at a 0.1 g displayed scale division but says its RS-232 interface is disabled. Buyers should choose based on the actual regulatory and data workflow rather than model number alone.
EK-6100i: finest process resolution and active serial data
EK-6100i gives 0.1 g readability over a 6,000 g range. It is the strongest fit of the three for internal laboratory, formulation, materials testing, production QC and inventory where tenth-gram changes matter and data must be sent to a PC or printer. It is not NTEP, so that fine process display should not be used as the legal basis for a regulated customer transaction.
EK-6000i: NTEP Class III with 1 g readability
EK-6000i trades one decimal place of process resolution for a specifically certified trade design. A&D U.S. lists it at 6,000 g × 1 g, NTEP Class III. It retains standard RS-232C and is one of the EK-i models approved for underhook weighing. Choose it when legal-for-trade status is required and a 1 g interval is appropriate for the commodity and jurisdiction.
EK-6100J: distinct legal-for-trade alternative
MNM’s EK-6100J product page explicitly contrasts the J and i versions: it calls EK-6100i non-NTEP and EK-6100J legal for trade, and says the J model’s RS-232 serial interface is not functional. That makes EK-6100J relevant when a particular trade configuration needs a finer displayed graduation and electronic data output is unnecessary. Do not assume EK-6100J and EK-6100i are the same device simply because the model names are similar.
Data connectivity comparison
EK-6100i and EK-6000i have standard RS-232C according to A&D/MNM. MNM says EK-6100J’s serial interface is disabled. A quality lab that needs automated electronic records may therefore prefer EK-6100i for non-trade work or EK-6000i when trade approval and 1 g readability are acceptable. If the transaction requires a different certified resolution, the legal metrology requirement can outweigh the data-connectivity preference.
Underhook and special weighing
A&D’s current accessory list supports EKW-07i underhook on EK-6100i and EK-6000i. That can make either model attractive for density/specific-gravity or suspended-load methods. For any formal test, verify the exact model, calibration and required resolution specified by the method; underhook availability alone does not determine compliance.
Which one should you buy?
Choose EK-6100i for 0.1 g internal process resolution plus active RS-232C. Choose EK-6000i for a current A&D NTEP Class III 6 kg × 1 g trade model with active serial data and underhook support. Evaluate EK-6100J when its particular legal-for-trade configuration is required and the lack of functional serial output is acceptable. Before purchasing for commerce, confirm that the chosen certified class/division matches the local application.
Frequently asked questions
Which has the finest process readability? EK-6100i at 0.1 g. Which one is A&D’s NTEP Class III EK-i model? EK-6000i at 6,000 g × 1 g. Is EK-6100i NTEP? No. Does EK-6100i have active RS-232C? Yes. Does EK-6000i have RS-232C? Yes. What does MNM say about EK-6100J serial data? Its RS-232 interface is disabled. Do EK-6100i and EK-6000i support underhook weighing? Yes. Should model number alone decide the purchase? No; use capacity, readability, trade status, interface and application requirements.
