A versatile industrial scale for weighing, counting, and product classification.

GRAM K3R is a robust industrial scale developed for production, packaging, pharmaceutical, and chemical environments where reliability and operational flexibility are essential. Its solid construction and high-resolution weighing cell ensure consistent performance, even under intensive daily use.

The scale supports a wide range of functions including standard weighing, piece counting, and weight-based classification, allowing operators to adapt the system to different tasks without changing equipment. With memory for multiple tares, products, and classification limits, GRAM K3R streamlines repetitive workflows and reduces manual input.

Thanks to its modular design, removable indicator support, and optional external platform connection, GRAM K3R can be configured for bench use, wall mounting, or integration with larger-capacity platforms — making it a highly adaptable solution for industrial operations.

PW-Link Software

PW-Link is GRAM’s software for real-time weighing data capture and reporting. It connects your scale to a PC via RS-232 or USB and records each weighing automatically — including date, time, weight, unit, and weighing number. The result is a live, structured table where weights are captured instantly, eliminating manual entry and reducing human error.

From weighing to reporting, everything stays simple. Users just select a cell and continue weighing while data is registered automatically. Weighing records can be exported to spreadsheet or PDF formats, branded with your company logo, and saved directly to a defined local folder — making documentation, traceability, and reporting fast and reliable wherever accurate weighing data matters.
