TOMELLERI ENGINEERING was founded in 1985, dedicating itself to research, design and construction of precise machines, instruments for astronomy and, in particular, the first Articulated Measuring Arms in Europe.


Initially the measuring arms were not portable in the way know them today, they were intended for measuring pipes and were equipped with only five axes.

In the following years, up to 2000, they received several improvements becoming portable and, therefore, lighter.

These improvments allowed the increase fo the number of axes, up to 7, and the increase of the measuring range, from the 2 m available at the time to 5 m, with way better accuracies.

In the last twenty years to the present day, TOMELLERI ENGINEERING has never stopped increasing the performance of its instruments and continued to work on new solutions suitable for different uses.

The new range of measures available makes TOMELLERI ENGINEERING arms the largest selection of the market, with instruments available from 1.2 m in diameter to the incredible size of 9 m.

These solutions are made possible by the long experience of the company on many fields where the accuracy is a design driver, making use of the team of expert engineers who, performing FEA analyzes and thanks to state of art software, develops innovative solutions covered by industrial patents.

The recently developed projects concern very high precision machines on small measuring ranges with new balance solutions, increasing accuracy in large measuring range machines, laser scanning devices, and special measuring software suitable for the most demanding needs.

Currently TOMELLERI ENGINEERING, thanks to the variety and quality of its products, is committed to increase its commercial penetration in the world, offering together a top quality service, based in particular on certification and calibration that can be performed at the final user's site.
