Hoffmann Group Connected Tools – Mobile App
Recording measurement data has never been easier
The HCT mobile app allows you to add additional features to your Bluetooth®-enabled tool. As a result, processes are integrated into the production flow even more efficiently, further improving the company’s standard of quality.

Using the HCT mobile app is very simple
As soon as the tools have been connected to the HCT mobile app via Bluetooth, measurement data captured on the tool can be sent to the smartphone or tablet. The app reliably saves all measurement data and outputs it all together in CSV format, including date of measurement, unit of measurement and many other parameters. The data sets can then be processed further in any PC application on the computer. Measurement parameters, target values and tolerance limits can be recorded in the app to make it easier to measure identical components. In the case of a deviation, a warning is issued to the user.
HCT-capable tools include dial indicators, calipers, torque wrenches and 3-point internal micrometers from the brands GARANT, HOLEX, Mitutoyo, Sylvac, Bowers Group and TESA. Further tools are constantly being added and can be found in this overview. As a result, tools for many different measuring operations are available to the quality management team in the workshop and production department.
