AU Series Semi-Micro and Analytical Balances
Advanced Functions Deliver Excellent Weighing Performance


AU Series Balances Model Lineup

The AU Series balances include AUW, AUX, and AUY model analytical balances and AUW-D model semi-micro balances, with minimum displays of 0.1 mg and 0.01 mg, respectively.

The UniBloc one-piece force cell technology at the heart of the balances provides excellent stability, reliability, and response, and is complemented by extensive features that support a wide range of weighing applications.


AU Series models:

  • AUW-D semi-micro balances, maximum weight range 42 g to 82 g

  • AUW analytical balances, maximum weight range 120 g to 320 g

  • AUX analytical balances, maximum weight range 120 g to 320 g

  • AUY analytical balances, maximum weight range 120 g to 220 g

Excellent Weighing Performance

Shimadzu’s compact UniBloc one-piece force cell and digital processing technology produce a stable, reliable, and fast weight response. Furthermore, the digital control can be set to automatically provide the most suitable data processing for the installation environment and weighing application.

Semi-Micro Models

The AUW-D models have dual-range weighing, with the option for semi-micro weighing. When using the semi-micro range, the AUW120D and AUW220D models have maximum capacities of 42 g and 82 g, respectively, with a minimum display of 0.01 mg.

A Multitude of Functions
AU Series Functions

The AU Series includes a multitude of functions applicable to a wide range of applications. The AUW, AUW-D, and AUX models possess multiple calibration functions. GLP, GMP, and ISO compatible reporting, an analog bar graphic display, piece counting, and a formulation mode are additional functions that improve workflow and efficiency, and are included in all AU Series models.

Optional Specific Gravity Measurement
Specific Gravity Measurement

Upon installing the optional SMK-401 specific gravity measurement kit, the AU Series balances are capable of measuring specific gravity or density. Measurements are simplified by the AU Series’ built-in specific gravity measurement mode.
