Price or readability? —BOTH!

When Your Budget Is Tight but Precision
Is Non-Negotiable...
Forget about those expensive electromagnetic force restoration*1balances. A&D's latest load cell technology employed in the EJ series
now challenges their established edge, oﬀering a way to spend lesswithout compromising on precision... and functionality as well!

High resolution (1/120,000 - 1/310,000) load cell as theweight sensor
The EJ series achieves a readability of 0.0002 g for a capacity of 22 g (lower capacity range of theEJ-54D2), 0.001 g for a capacity up to 310 g (higher capacity range of the EJ-54D2 and EJ-123/303),
or 0.01 g for a capacity up to 3100 g (EJ-1202/3002).
It is suitable for use in diverse applications in schools, laboratories and factories that require
highly precise measurement. Meanwhile, the use of a load cell instead of an electromagnetic
force restoration sensor keeps its prices surprisingly aﬀordable.

Makes the weighing results easy to readeven in a dimly-lit area.

Method most commonly adopted for balances with resolutions of one over several hundred*1 thousandor higher. It determines a mass from the amount of current required to generate the*electromagnetic force on one side of a lever that equalizes with the mass placed on the other side.

2 The breeze break of the EJ-54D2 is opened by sliding its upper surface to keep air turbulence to aminimum.

Extremely high sensitivity (EJ-54D2)
The EJ-54D2, a dual range model, has two weighing ranges with diﬀerent capacities andreadabilities, each range extending from zero to its capacity. The readability of the lower
capacity (22 g) range is as ﬁne as 0.0002 g (or 0.001 ct), which, for example, is ideally suited for
precisely weighing/counting small pieces of precious metals/jewelries*3.
carat pan is provided for the EJ-54D2 and can be used instead*3 Aoffree
the standard weighing pan. The breeze break can be easily
detached for changing the pan as well as for cleaning (see below).

EJ-54D2

Meanwhile, the readability of the larger capacity(52 g) range is 0.001 g, which is the same as theEJ-123/303. The balance switches between the twoweighing ranges either automatically or by manual
operation depending on the internal setting.

Useful options
Data communication interfaces*4■ Quick USB interface (EJ-02), which allows you to send weighing data to Microsoft Excel, Word,
Notepad, etc., without installing any drivers or other additional software on a PC*5
■ RS-232C interface (EJ-03) for bi-directional communication with a PC, printer or otherperipheral devices
one interface can be installed at a time.
*45 Only
For transferring weighing data from the balance to a PC only. Please use the RS-232C interface* with the AX-USB-9P serial/USB converter for bi-directional communication or GLP output via USB.

Density determination kit (EJ-13)*6
The balance can automatically calculate a density from the sample
weight in air, sample weight in water and water temperature.

Other features*6 For the EJ-123/303 only

EJ-13

✔ Adjustable response characteristics and display hold function tobe used depending on the weighing/environmental conditions✔ Counting mode with Automatic Counting Accuracy Improvement(ACAI) function✔ Percent mode function to display the weight value as a percentage of a reference mass
✔ Accumulation (M+) function to display the sum total of separate weighing results✔ Multiple units of measure: g, oz, lb, ozt, ct, mom, dwt, gr, N, pcs (counting mode) and %(percent mode), in addition to SG (density mode)*7✔ GLP/GMP/GCP/ISO compliant output to meet documentation requirements✔ Operation with either AC adapter or four AA batteries✔ Auto power OFF function to avoid wasting powert (tola) or tl (tael - HK general/Singapore, HK jewelry, or Taiwan) can*7 Eitherbe added upon request, and lb is not available with the EJ-54D2/123/303.
