The range of Hoffmann Group Connected Tools (HCT) products is expanding and helping torque technology become more systematic. The first electronic torque analyser of the GARANT brand is setting new standards with its unique functions, connectivity to other HCT products, its simple operation and digital documentation capability. This Bluetooth-enabled device checks the accuracy of torque tools with a tolerance of plus or minus one percent. It has a memory that can store up to 1000 measurement values with a timestamp and 20 configurable test cases. The measurement data is evaluated automatically and can be transferred as a CSV file via USB cable to a computer, or wirelessly via Bluetooth to the free HCT smartphone app.

The GARANT electronic torque analyser HCT can be used to check the accuracy of mechanical and electronic torque wrenches or torque screwdrivers from any manufacturer. The device features the three usual measurement modes: “Tracking display” (Track), “Trigger point sensing” (First Peak) and “Peak value display” (Peak Hold). During the measurement, the user receives both a visual signal (via the high-contrast 2.8-inch TFT colour display with stable viewing angle) and an acoustic signal to indicate when the set target range has been reached. The device automatically evaluates whether the measured peak value is within the set target tolerance. The result is displayed in green if the value is within the target range and in red if the value is outside of the target range and saved in the device’s internal memory. The available units of measurement are Newton metres (Nm), Foot-Pound-Force (lbfft) and Pound-Force-Inch (lbfin), and the menu language can be set to either German, English, French, Italian or Spanish.

Using the device in combination with HCT-ready torque tools opens up even more special system features for the user. The open Hoffmann Group Connected Tools (HCT) platform enables the tools to communicate with one another. The torque analyser can be connected to an HCT torque wrench via Bluetooth and then show both its own value and that of the torque wrench on the display, enabling the user to keep an eye on the relevant values at all times. The device can also be used to unlock HCT torque wrenches that have been locked as a result of overloading. This eliminates unnecessary downtimes, as the torque wrenches no longer have to be sent off to be unlocked.
In the free HCT smartphone app, the set test case parameters and the evaluated measurement results are displayed and can be exported as a CSV file. The smartphone app also allows the user to download the latest device software to the torque analyser via Bluetooth, thus enabling new extended functionalities to be accessed. The device will become even more convenient when it is able to load data into a quality assurance system (CAQ) via the HCT Windows app – a functionality that will soon be available. This means that, before a work process begins, torque tools can be checked via operator guidance and the results documented together with other information about the component or assembly.

Hoffmann Group Connected Tools (HCT)
The Hoffmann Group is promoting digitalisation in the tooling sector through the open Hoffmann Group Connected Tools (HCT) platform. Currently compatible with the HCT platform are Bluetooth-enabled vernier calipers, dial indicators, torque wrenches and 3-point internal micrometers under the GARANT, HOLEX, Mituyoyo, Bowers Group and Sylvac brands. The circle of notable brand manufacturers expanded most recently through the connection of the wireless system Tesa TLC, via which vernier calipers and height gauges under the Tesa brand can send measurement data to the HCT smartphone app.
