micro analytical weighing module

A&D's AD-4212D series of micro analytical weighing sensors (readability from 1 μg) are high-end balances used for embedding in production-line weighing systems. They are also perfectly suited for use inside laboratory equipment where ordinary analytical balances are unfit for installation or for stable measurement.

The AD-4212D employs what A&D calls EM-DLC, or Electromagnetic Digital Load Cell, technology. The weighing sensor has an integrated A/D converter and can output weighing results as digital data directly to a PC or PLC. This saves space when you do not need or have room for installing the separate display unit in production lines.

Meanwhile, in laboratories, the compact size of the AD-4212D is ideal for installation in narrow spaces such as inside a glove box. Moreover, since the AD-4212D is independent of delicate electric parts used in a display unit, it can easily withstand a vacuum state caused during gas displacement of a glove box.

Also, thanks to its small body, the AD-4212D series is less susceptible to the effects of drafts compared with standard analytical balances, which receive the force of the wind more squarely. Therefore, when used with the provided small breeze break, the AD-4212D series can stably measure even in a fume hood where turbulent airflows are constantly present (with 0.1 mg readability only).

All four models in the AD-4212D series have an internal calibration function to ensure accuracy quickly and easily. They also come standard with the AD-1691 weighing environment analyzer with a color touch-panel LCD that can be used to not only display weighing results but also perform calibration, change internal settings, etc.
