A series-production line of electronic torque wrenches. The tool is the Open Protocol server. No gateway, no installed software.
Connected tools from the big names still need a controller or a gateway to reach the plant floor. Ours does not. Software already lives in the wrench, and every tightening result travels to where it is needed.
Nothing to install and nothing to license. Connect over USB, Bluetooth, or Wi-Fi, open Chrome or Edge, and work offline: presets, calibration, traceability, and MES integration.
The configurator served by the wrench drives an automatic, multi-point calibration and verification against a reference stand: target points, tolerances, live deviation per point, and a traceable protocol at the end. Following ISO 6789, with nothing to install.
Every unit is designed around real assembly lines: serial cycles, traceability requirements, and direct integration with the systems that record them.
An on-board Open Protocol server. Your MES reads every result over Wi-Fi in real time, with no gateway or controller in between.
Gyroscope angle with auto zero. Every tightening captured as a full trace, on every model.
Digital torque to 0.02 Nm resolution on the low ranges. Factory calibrated, ISO 6789 wizard on board.
Torque, angle, time, and pass or fail on each pull. Full results.csv archive on SD, CSV export.
Aircraft aluminium and carbon housing. Drop and impact sensors plus usage counters record real conditions.
Firmware for the compute module and the radio module updates straight from the browser. The tool keeps gaining capability over its service life.
4 to 1200 Nm · ±2% · torque and angle on every model · series production today.
Large figures read from a distance, and three themes match the light of the bay. The same display runs on every GN series.
One connected platform covers the whole assembly station, from small fasteners to flange joints. Enter the tightening torque and we show the models that fit, smallest sufficient limit first.
For 100 Nm: 0 models fit
Smallest sufficient limit first: more accurate, and lighter in the hand.

The hardest thing to prove in a first email is that the product is real and shippable. It is. A full line is in series production today, and evaluation units are ready to go out.
Book a demoSix series from 4 to 1200 Nm, manufactured today, not a roadmap.
Evaluation units reach a partner before the call, with live demo access.
On-board calibration wizard. CE (RED) and accredited ISO 6789-2 calibration underway.
Aluminium and carbon housing, IP54, drop and impact sensors, removable standard cell.
Every part of how we build and how we talk runs on our own servers: source control, CI, task planning, test and verification, and every message, call, and screen share. No third-party cloud sees a line of your project.
Version control, continuous integration, task planning, and test and verification run in-house, on hardware we control. Code never leaves the building.
Chat, voice, video, and screen sharing are self-hosted and encrypted. A call about your firmware never routes through a vendor's data center.
A zero-trust mesh links our machines with centralized access and a full audit trail. We know exactly what moves, and where.
The same closed environment extends to a partner's team on demand, under one access model and full control of what is shared. We open a door, not the whole house.
For an OEM or licensing partner, that is the difference between trusting a promise and trusting an architecture.
G&N Devices does not sell to end users. We supply and license the platform to the brands, distributors, and manufacturers who take it to market.
Add a complete electronic torque wrench category under your own brand this year, with zero R&D. A ready line of 31 models, your packaging and documentation, shipping in series.
License the stack that turns a tool into an Open Protocol server: the on-board browser configurator, ISO 6789 calibration, and over-the-air updates. Faster and cheaper than building it in house.
Bring the connected-wrench architecture into your platform: direct MES connection with no controller, angle and trace, proven across a 31-model production line.
Platform-level parameters. Exact values for a given model are on its device passport and quotation.
Series-production units are ready to ship to evaluation partners. Book a short call and we will send a sample and live demo access in advance.
