Indicators & Terminals
GRAM MK is fully compatible with GRAM’s digital indicator family — K3X, K3iX, K3W, K3iW — as well as the Z8 and Z8i weighing terminals, via cable or optional Wi-Fi, providing 3-colour checkweighing, advanced tare management, and totalisation.
Printers
GRAM MK works seamlessly with GRAM’s printer ecosystem through its K3 indicator compatibility — supporting the PR4 compact thermal printer and the Q2 label/ticket printer for reliable documentation and traceability. The system also supports the RD3 repeater display, providing clear, high-visibility weight information in remote or elevated positions.
Connectivity, Software & Data Integration
The GRAM MK kit offers secure connectivity through RS-232C and optional Wi-Fi, enabling direct communication with PCs, indicators, smartphones and industrial controllers.
The internal Xtrem® module stores all calibration and configuration data and can send measurements directly to any device on the IP network — including PCs, tablets and Android smartphones — without requiring an external indicator.
Compatible with Xtrem PC Software, EX Link, PW Link and the Xtrem App, it supports real-time visualisation, CSV export, QR-code output, multi-device management and remote configuration.
Mounting, Cables & Accessories
A full range of accessories is available to support installation and integration: painted or stainless-steel bases with column for indicator mounting, stainless U-tube supports, wall brackets, and ABS swivel bases.
Connectivity options include Direct K USB, RS-232 cables for RD3 and printers, K3-to-K3 remote cables, and digital add-ons such as the 3-relay output, RTC board or Wi-Fi board.
Certification & Calibration
Optionally available with ISOCAL certificates.
These provide individual calibration data and full traceability to support quality systems in accordance with ISO 9001.
