A&D Weighing AD-4212B-23 AD-4212B Series Production Weighing System, 21 g x 0.001 mg

The A&D AD-4212B-23 provides a maximum weighing capacity of 21 g with an ultra-fine 0.001 mg (1 microgram) readability. It offers repeatability of 0.003 mg from 0–10 g and 0.004 mg from 10–21 g, along with ±0.01 mg linearity. This level of sensitivity makes it suitable for extremely precise production and measurement applications.

The AD-4212B-23 is designed for ultra-precision production and in-line weighing where microgram-level measurements are required. Typical uses include precision filling, checkweighing, small-component measurement, and enclosed production processes where very small changes in mass must be detected.

The AD-4212B-23 has an approximate 12-second stabilization time when operated under suitable environmental conditions. While this is slower than lower-resolution AD-4212B models, the additional stabilization time supports the model's exceptionally fine 1 µg readability.

Yes. The AD-4212B-23 provides bi-directional RS-232C communication and can be connected to compatible computers, PLCs, data loggers, and production-control equipment. A&D also supports Ethernet/LAN connectivity through an appropriate converter, giving system integrators additional options for incorporating weighing data into automated processes.

The AD-4212B-23 uses external calibration. A&D documentation also identifies an OIML Class E2-equivalent calibration weight with the system, supporting high-accuracy calibration and routine performance verification in demanding production and quality-control applications.
