Industrial Simplicity. Operational Efficiency.

The GRAM K3 series is a high-performance weighing indicator designed for production lines, quality control, packaging stations, goods reception, and dispatch environments.

Its intuitive cross-shaped keypad allows fast navigation and configuration, enabling operators to switch between weighing modes, classification limits, and piece counting within seconds. Advanced software functions such as automatic tare, last weighing memorization, dosing at two speeds, and accumulation ensure that daily workflows run smoothly and efficiently.

K3 is not designed to impress on paper — it is designed to perform on the floor. Reliable, adaptable, and easy to integrate, it brings practical intelligence to industrial weighing processes.
