GRAM Zebra integrates seamlessly with GRAM’s digital indicators — K3X, K3iX, K3iX-P, K3W, K3iW — as well as the Z8 and Z8i weighing terminals, via cable or optional Wi-Fi.
All compatible models support 3-colour checkweighing, multi-tare memory, totalisation, date and time-stamped ticket printing, and high-resolution display modes.
Powered by the platform’s integrated Xtrem® digital module, all calibration and adjustment data are securely stored within the system.

Through its K3-series compatibility, GRAM Zebra integrates with the PR4 compact thermal printer and the Q2 label/ticket printer, both connected via RS-232C. These printers enable accurate, reliable documentation for industrial workflows.
For wireless, smartphone-based label generation, Zebra also supports the Q1 Bluetooth label printer, used via the Xtrem App with Premium activation.

GRAM Zebra is designed for advanced multi-channel connectivity, providing RS-232C as standard and offering optional Wi-Fi, Ethernet or RS-485 modules for more demanding setups. Its integrated Xtrem® digital core ensures secure, autonomous operation, allowing the bars to transmit data directly to indicators, PCs, tablets or Android smartphones without the need for intermediary hardware. When connected via Wi-Fi or Ethernet, GRAM Zebra can operate within a centralised multi-device network, and its built-in Web Server enables browser-based data capture through Chrome, Edge or Safari. The system works seamlessly with PC Xtrem for legally verified PC-based indication, with PW Link for real-time display and CSV export, with EX Link for efficient data capture and record management, and with the Xtrem App for Android, which supports multi-terminal use, label printing, barcode scanning and enhanced traceability when the Premium option is activated.

The system integrates with GRAM’s complete installation ecosystem, including stainless-steel and painted steel indicator stands with 930 mm columns, stainless U-shaped wall brackets and ABS swivel supports.
Connectivity accessories include ZLink® digital cables — standard 4 m and optional 8 m or 15 m lengths — plus RS-232C printer/PC cables, USB output modules and Direct K smart USB connections.
For structural installation, Zebra can be mounted using fixed foot plates, enabling stable, secure integration into cages, frames or custom weighing structures.

GRAM Zebra supports the RD3 remote repeater display, which provides large, high-visibility weight readings for elevated or distant mounting locations.
It is also compatible with the three-level LED traffic light, offering immediate colour-coded feedback for checkweighing, sorting and process-control tasks.

Optional ISOCAL calibration certificates are available for GRAM Zebra. These certificates provide individualised calibration data across all capacity ranges, supporting ISO-aligned quality systems, internal audits and traceable maintenance routines.
