EW precision balance – Robust tuning fork balance for exact measurements

The EW precision balance with a round weighing plate 118 mm in diameter is the proven classic among laboratory balances. Thanks to the robust tuning fork weighing system, it impresses with precise measuring results, long service life, and high mechanical stability.

With the integrated CAL adjustment program, the balance can be easily adjusted to ensure maximum accuracy. Optionally, test weights can be purchased for extended measurement checks.

The balance is characterized by stable temperature behavior and short stabilization times, which enables fast and precise weighing. The high off-center loading safety guarantees reliable results even with unevenly distributed loads.

Additionally, the balance supports totaling. For additional protection, a working protective cover is included, as well as a draft shield, which ensures measurement accuracy during slight air movements.

Product advantages at a glance:

  • Robust tuning fork weighing system for precise measuring results

  • CAL adjustment program for easy adjustment

  • Stable temperature behavior and fast stabilization times

  • High mechanical robustness and off-center loading safety

  • Totaling function

  • Includes working protective cover and draft shield

The EW precision balance is the ideal solution for laboratory, industrial, and precision applications, where reliable and exact weighing is crucial.
