Check Weighers

Checkweighers Overview

Checkweighers are automated systems that verify packaged product weights in real time on production lines, rejecting under- or overweight items to ensure regulatory compliance (e.g., UK Weights & Measures) and minimise giveaway—essential for food manufacturers facing BRC audits and rising ingredient costs.

Dynamic models like the LOMA CW3 series dominate food processing, handling speeds up to 120 m/min with IP65/IP69K washdown ratings, touchscreen controls for 500+ product setups, and integration with fillers for automatic mean-weight correction.
