Affordable Precision

Now students, researchers and industrial users
have a convenient and affordable way to make
milligram measurements.

The EJ’s have standard functions usually found
in balances costing twice as much:

- Gravity correction

- Accumulation M+ Function

- GLP/GMP/GCP/ISO Compliant

- Auto Counting Accuracy Improvement ACAI

- Adjustable response characteristics

- Display Hold

Draft shield standard
on EJ-123 and EJ-303

The EJ-303 and EJ-123 make milligram
measurements as easy as, well, 1-2-3:

1. Plug-in and warm-up the balance.

2. Level the balance by adjusting the feet.

3. Start weighing.
