440 Precision Balance Series – Compact High-Accuracy Laboratory Weighing

The 440 Precision Balance Series provides reliable, high-accuracy weighing in a compact and practical laboratory balance design. Ideal for laboratories with limited bench space, these balances combine precision, stability, and user-friendly functionality for everyday laboratory measurements.

A key feature of the 440 series is percentage determination, allowing users to store a reference weight (100%) and quickly measure deviations. This function is especially useful for quality control, formulation, and comparative weighing applications.

Each balance is equipped with a ring-shaped draught shield (⌀ × H 90 × 40 mm) to protect samples from air disturbances, ensuring stable and accurate readings. A protective working cover is also included for safe operation and durability.

With RS-232 connectivity for data transfer and external calibration for long-term accuracy, the 440 Precision Balance series remains a trusted choice for laboratories, quality control departments, and educational institutions.
