A&D EK-i Series High Capacity Compact Balance

A&D EK-i Series High Capacity Compact Balance (NMI Trade Approved)

The EK-i Series High Capacity Compact Balance represents a comprehensive range of high-accuracy, portable top pan precision balances specifically designed for demanding industrial and laboratory weighing applications. Offering a wide selection of 16 different models with capacities ranging from 30g to 12kg and resolutions from 0.01g to 1g (with exceptional 1/60,000 high resolution available in select models like EK-610i and EK-6100i), the EK-i series delivers the versatility required for diverse weighing scenarios. Trade Approved by NMI Australia (NMI #6/4C/243), these balances are designed to meet weights and measures regulations of various countries including NTEP and EC compliance, making them suitable for legal-for-trade applications. The series features a rugged, low-profile housing with sealed key panel protection against dust and spills, stainless steel weighing pans, and a large 7-segment LCD display with 16mm character height and backlight for easy reading even in wide viewing angles or dark environments—all packaged in a portable-compact, lightweight design with a small footprint that fits any space requirement. The triple-range design is particularly valuable for jewellery weighing, where users can switch seamlessly between high-resolution modes for small gemstones or precious metal fragments and higher-capacity modes for larger items or batches — all with NMI trade approval for legal transactions.

Built for reliability and advanced performance, the EK-i series incorporates standard RS-232C interface for seamless data communication, full digital calibration with optional user-definable mass settings, and GLP conformity with I.D. and serial number outputs for regulatory compliance and traceability. The balances feature 9 built-in weighing units plus counting and percentage modes with user priority start-up, counting function with Automatic Counting Accuracy Improvement (ACAI) for enhanced precision, and a standard comparator function with HI/OK/LO annunciator for quality control applications. Power versatility is ensured through AC adapter or optional rechargeable Ni-MH battery pack operation, while auto power-off functionality conserves energy during periods of inactivity. Optional underhook weighing capability (available for EK-4100i, EK-6100i, EK-6000i, and EW-12Ki models), leveling feet with level bubble for accurate setup, security ring for theft prevention, and overload protection make the EK-i series an exceptionally robust solution backed by a comprehensive three-year warranty. Free downloadable WinCT software is available for enhanced data management and analysis capabilities.

Trade Approved Balance Verification Certificate

When a balance receives NMI/NSC certificate of approval, it is certified under a specific accuracy class that defines the performance parameters required for legal-for-trade applications. A critical parameter is the verification interval—the minimum certified increment for trade use. Due to the high number of internal divisions in modern balances, the verification interval for trade approval typically differs from the balance's display resolution. For example, the GX-4002A displays weights to 0.01g, but its trade-approved verification interval is 0.1g.

Most trade-approved balances continue to display finer increments (often indicated by brackets or similar notation), though some models like the Class III EK-i completely suppress the last digit, while the EW-150i eliminates an entire range. The verification interval represents the certified accuracy for legal-for-trade purposes and is the official measurement increment recognized for commercial transactions. To assist in selecting the appropriate balance, our trade-approved models are listed with their accuracy class and verification interval specifications.

• NMI Trade Approval — All EK-i models are NMI Trade Approved (NMI approval number: #6/4C/230).
• NMI Verification Certificate — By Australian law, any NMI Trade Approved model must have an official NMI Verification Certificate before it can be used for trade purposes. This certificate is available from us for an additional fee

Specifications

A&D EK, EK-i, & EW-i Series Compact Balance Comparison:

• EK Series This is the latest generation high-resolution model in the Equa line. It builds on the success of the EK-i with enhanced performance, improved capacities, and refined electronics while maintaining the same compact and durable design.
• EK-i Series (High Capacity) The well-established high-precision single-range balances. Ideal when you need consistently fine readability (e.g. 0.01 g) across the entire capacity. Great for labs and applications requiring high accuracy.
• EW-i Series (NMI models available) The versatile “all-rounder”. It features triple-range technology — the balance automatically changes resolution depending on the weight placed on it. This makes it very practical when you regularly weigh both very light and relatively heavy items on the same scale.
  

Which one should you choose?

• Need the highest possible accuracy? → Go with the EK Series or EK-i Series.
• Need flexibility to weigh a wide variety of items without switching balances? → Choose the EW-i Series.
