Precision scale EW – Robust tuning fork scale for precise measurements
The EW precision balance with a round weighing surface measuring 118 mm in diameter is a time-tested classic among laboratory balances. Thanks to its robust tuning fork weighing system, it impresses with precise measurement results , a long service life , and high mechanical stability .
The integrated CAL calibration program makes it easy to calibrate the scale to ensure maximum accuracy. Optional test weights are available for advanced measurement checks.
The scale features stable temperature behavior and short settling times , enabling fast and precise weighing . The high corner load safety guarantees reliable results even with unevenly distributed loads.
The scale also supports totalizing. For additional protection, a protective cover is included, as is a windshield that ensures measurement accuracy even in light airflow.
