The A&D EK-1200i Compact Balance combines a 1200 g weighing capacity with 0.1 g readability in a compact benchtop design for laboratory, production, food and beverage QA/QC, education, parts counting and general industrial weighing.
Part of A&D's long-running EK-i Series, the EK-1200i features a SUS304 stainless steel weighing pan, backlit LCD, standard RS-232C communication, external calibration, counting with ACAI, percentage weighing and HI/OK/LO comparator functions.
Its rectangular 170 × 133 mm weighing pan provides useful working area for beakers, sample containers, trays, bags and small components while the complete balance occupies only approximately 190 × 218 mm of bench space.
The EK-1200i measures from zero to 1200 g with 0.1 g increments, providing 12,000 displayed divisions.
This capacity/readability combination works well for applications that need greater precision than a typical 1 g bench scale without requiring the 0.01 g or 0.001 g resolution of a higher-cost laboratory precision balance.
Typical weighing applications include:
The EK-1200i has a readability and repeatability of 0.1 g. It is not a milligram balance. Applications requiring 0.01 g, 0.001 g or finer readability should use a higher-resolution A&D balance.
A&D equips the EK-1200i with a 170 × 133 mm SUS304 stainless steel weighing pan.
The rectangular pan provides enough surface area for many common laboratory and production containers, including:
Stainless steel provides a durable, easy-to-clean weighing surface for routine laboratory and industrial use.
The EK-1200i measures approximately 190 mm wide × 218 mm deep × 53 mm high, allowing it to fit on crowded laboratory benches, production workstations and classroom tables.
Approximate net weight is 1.5 kg, making the balance relatively easy to relocate when required.
Adjustable feet and an integrated spirit level help the operator establish a level weighing surface before calibration and use.
The EK-1200i uses a 7-segment backlit LCD with 16 mm-high characters for easy reading.
A&D specifies a display update rate of approximately 10 times per second, while the balance provides an approximately 2-second stabilization time under appropriate weighing conditions.
The backlight can be configured for automatic operation, continuously on or off depending on the application.
The EK-1200i includes a dedicated parts-counting mode with A&D's ACAI technology.
ACAI – Automatic Counting Accuracy Improvement continually improves the calculated unit weight as additional pieces are placed on the pan.
This can improve counting accuracy compared with relying only on the original small reference sample.
EK-1200i counting specifications include:
Counting mode can be useful for hardware, fasteners, small components, packaging parts, inventory checks and production quantities.
Percentage mode displays a sample's weight relative to a stored reference weight defined as 100%.
For the EK-1200i:
Percentage weighing can be useful for formulation checks, sample comparisons, ingredient ratios and production consistency.
The built-in comparator function allows upper and lower limits to be established so the EK-1200i can identify whether a weighing result is:
This is useful for repetitive checkweighing applications such as verifying package contents, sample quantities, components or production weights.
An optional comparator relay output and buzzer is also available where external signalling is required.
Unlike many basic compact balances, the A&D EK-1200i includes a standard RS-232C serial interface.
The interface can communicate with compatible:
RS-232C can also receive supported commands, allowing external control of selected balance functions.
The EK-i platform supports structured documentation output through the serial interface.
Depending on the connected equipment and configuration, output can include information such as:
This can help laboratories maintain more organized weighing and calibration records.
The EK-1200i provides functions designed to support GLP/GMP/GCP/ISO-style documentation. The balance itself does not make a laboratory or weighing procedure compliant with a particular regulatory or quality standard.
The EK-1200i uses external weight calibration.
A&D lists 1200 g as the factory calibration-weight setting, although the balance provides settings for performing calibration with an appropriate external mass.
For QA/QC applications, use calibration or verification weights appropriate to the accuracy requirements of your weighing program.
Calibration frequency should be determined by the balance's use, environment, quality system and risk associated with an incorrect weighing result.
The standard EK-1200i operates from its AC adapter. A&D also offers an optional Ni-MH rechargeable battery pack for cordless weighing.
A&D's current EK-i instruction manual specifies approximately 9 hours of continuous battery operation with the LCD backlight switched off.
The rechargeable battery pack is not part of the standard EK-1200i configuration unless specifically included in the quotation or product package. Do not confuse the EK-i battery specification with the much longer battery life published for A&D's separate EK-AEP intrinsically safe series.
A&D allows the balance's response characteristics to be adjusted to help accommodate different weighing environments.
A faster response may be useful on a stable bench, while a slower response setting can improve stability when vibration or air movement affects the displayed value.
For best performance, place the EK-1200i on a firm, level surface away from strong drafts, vibration, direct sunlight and rapid temperature changes.
The 1200 g capacity, 0.1 g readability and stainless weighing pan make the EK-1200i useful for many non-trade food and beverage laboratory applications.
Potential uses include:
Where weight is used to determine the price charged in Canada, confirm that a Measurement Canada-approved device is being used instead.
The EK-1200i provides a practical balance for laboratories that need 0.1 g resolution over a relatively large 1.2 kg capacity.
Typical uses can include:
The comparator and counting functions make the EK-1200i particularly useful outside the traditional laboratory.
Potential production applications include:
The compact footprint, straightforward controls and multiple application modes also make the EK-1200i useful for educational laboratories.
Students can perform general weighing, percentage calculations, parts counting and data-output exercises on the same instrument.
The EK-1200i is covered by U.S. NTEP Certificate of Conformance 04-019A3 as a Class II device.
NTEP approval is not the same as Measurement Canada approval.
Canadian businesses using weight to determine the price of a product require a device approved for measurement-based trade in Canada under the applicable Measurement Canada requirements.
Do not purchase the EK-1200i solely on the basis of its NTEP approval if your application requires legal-for-trade weighing in Canada. Contact Cambridge with your application and we can help identify an appropriate Measurement Canada-approved model.

The EK-1200i is covered by NTEP Certificate of Conformance 04-019A3 as a Class II device. Local U.S. weights-and-measures requirements still apply to commercial use.
NTEP approval does not by itself authorize a scale for measurement-based trade in Canada. A Canadian trade application requires the applicable Measurement Canada approval and inspection requirements. Contact Cambridge if your weighing result will be used to determine a selling price.
The EK-1200i uses a rectangular 170 × 133 mm SUS304 stainless steel weighing pan.

If you are unsure whether the EK-1200i has enough capacity or resolution for your application, send us your maximum expected weight, smallest weight change you need to detect, container size, calibration requirements and whether the balance will be used for measurement-based trade.
Capacity alone does not determine the correct balance. Readability, repeatability, pan size, calibration requirements, data connectivity and whether the application is legal for trade can all affect model selection.
Send Cambridge your weighing application and we can help identify the appropriate A&D model.
