A Newly Developed Load Cell Realizes Extremely Cost-effective 1 mg Balances for Schools and Colleges

In particular, these models have been developed with use in educational settings in mind, as such institutions are often on a strict budget while in need of securing a sizable number of units for classes, experiments, etc. Since in this market balances are typically sought through on-line stores and catalogs, their color design is made especially eye-catching, albeit uncharacteristic of A&D, to stand out in these media.

On top of superior basic performance as a weighing device, the EJ-123/303 provides various powerful features. For example, depending on the degree of drafts and vibrations at the location, the user can select one of three different combinations of weighing speed and stability to elicit the optimal performance possible under the given environment.

To make a range of weighing applications easier, the EJ-123/303 is equipped with functions like counting mode, percent mode, accumulation (M+) function, and display hold function. Weights can be shown in gram, ounce, troy ounce, metric carat, pennyweight, grain, or Newton. Further, using the optional density determination kit (EJ-13), the user can have the balance calculate the density of a sample automatically.

The EJ-123/303 comes with a breeze break with anti-static coating as standard, to ensure stable weighing by shielding drafts as well as static from nearby objects. Its stainless steel (SUS304) weighing pan is resistant to scratches and wear, and is easy to clean and keep hygienic. In the rear of the balance is a security slot to accommodate an off-the-shelf (such as Kensington) anti-theft lock.

Finally, two optional interfaces are available. One is the Quick USB (EJ-02), which allows weight data transfer to a PC USB port (one way) requiring no special software/driver installation. The other is the RS-232C (EJ-03), with which bi-directional communication and GLP/GMP/GCP/ISO compliant output become possible. The EJ-123/303 can be operated with either an AC adapter or four AA batteries (for approx. 80 hours with alkaline batteries, backlight off).
