Fast, stable weighing with tuning fork sensor

The Kern EW and EG Series precision balances are designed for dependable, high-accuracy weighing in laboratory and industrial environments. They feature a robust tuning fork measuring system for rapid stabilization and reliable results, making them ideal for repetitive and time-sensitive tasks.

The EG series includes internal adjustment, ensuring precision regardless of location or environmental changes. The EW series requires external calibration and is optimized for budget-conscious users who still need professional-grade performance. Both series come with compact, durable housing, a large LCD display, and optional accessories including draft shields and rechargeable batteries.
