EW Precision Balance Series – Reliable Laboratory Weighing with Tuning Fork Technology

The EW Precision Balance Series is a classic and reliable weighing solution designed for laboratories, chemical industries, precious metals trading, and industrial quality control. Built with a robust tuning fork measuring system, the EW series delivers fast stabilisation, excellent temperature stability, and long-term accuracy, making it ideal for demanding precision weighing tasks.

These balances are engineered to deliver high repeatability, durable performance, and consistent measurement results, even under intensive daily use. With multiple weighing units and user-friendly functions, the EW series is suitable for analytical laboratories, manufacturing environments, and jewellery or precious metals applications.

High-Performance Tuning Fork Weighing System

The EW precision balance range features advanced tuning fork technology, offering several advantages over conventional weighing systems:

  • Stable temperature behaviour for reliable measurements

  • Fast stabilisation times (2–3 seconds) for efficient workflows

  • Shock-proof construction for long-lasting durability

  • Excellent corner load performance for consistent weighing across the pan

These features ensure precise, repeatable results across a wide range of laboratory and industrial weighing applications.

Practical Features for Efficient Weighing

The EW series includes several user-focused features designed to simplify daily weighing tasks:

  • A capacity bar graph display showing the remaining weighing range

  • Tolerance weighing with a visual signal for quick pass/fail checks

  • Piece counting with a totalising function for inventory and production use

  • RS-232 interface for easy connection to computers, printers, or laboratory software

  • Protective working cover is included for long-term protection

  • External calibration (CAL program) for quick accuracy adjustment using test weights
