One-Too

For 50 years, One-Too has been a French company that designs and distributes innovative tools, especially for the transport sector and more particularly for car repair.
One-Too has established a reputation as an expert in the design and manufacture of custom-made industrial metrology systems: acquisition, evaluation and characterization of physical quantities.


Concretely, this expertise is the source of great successes such as:
• Our belt mounting solutions, such as Install Auto
• Our belt tensiometers for belt tension measurement, such as Newten, Diapaz or Cycl'opt
• Our screw-on assembly solutions, with the Moment Alpha Torque and Angle Electronic Torque Wrench for Industries and Garages
• Our Audiobox Sound Level Meter, a sound detection solution
• Our Amédée compressiometer, for physical size acquisition
• Our Testair Tire Pressure Monitor
• Etc.

Our solutions will save you time, efficiency and reliability.

This know-how is the result of proven methodologies and close collaboration with our partners, but also of a carefully maintained state of mind for more than 50 years.
Our experts are at your disposal to study your specific needs and provide you with a solution to improve your productivity and the quality of your services.

A human adventure:

The epic One-Too is above all human. Our company has grown thanks to the men and women who have worked for it with passion since 1971, as well as those who work alongside us as partners.

We want to preserve this human philosophy, of proximity, both within our teams and with our partners.

Useful innovation:

«It seems that perfection is reached not when there is nothing left to add, but when there is nothing left to take away» Antoine de Saint-Exupéry

For us at One-Too, the perfection of innovation is the right balance, the one that offers a high efficiency index by reducing what is useless.

The Amédée compressiometer, symbol of useful innovation

Homage to Amédée Gordini, Amédée is a solution for controlling the top of cylinders of thermal engines.

A tool for mechanics: the responsible automotive specialist who analyzes before performing the surgery.
A secure tool equipped with the ISO Kit, consisting of a pressure gauge and a nozzle
An economical tool that helps fight waste.
The Amédée compressiometer extends the life of repairable motors rather than replacing them.

Listening and anticipation:

To innovate effectively and offer tailor-made solutions, it is necessary to be attentive to the current needs of the market and to anticipate its future needs.

These capacities of listening and anticipation have forged the history of our company and are always one of our strengths. Initially an expert in the control of carburettors, these two values allowed us to specialize in the installation and measurement of belt tension. Then to become more globally an expert in the design and manufacture of industrial metrology systems, for the automotive, mechanical industry and aeronautics.

Building sustainable partnerships:

All our products come from close collaborations. It is these close relationships that enable us to identify the needs of our customers and offer them tailor-made solutions.

More than just the customer relationship, we place a great deal of importance on creating long-lasting, trusting partnership relationships to support our customers over time, to monitor and understand their needs and to respond to them effectively.

The One-Too Hub: more than a network of partners

Future solution, new way of working, the One-Too Hub is a network of expert partners. In a spirit of confraternity, complementary companies work hand in hand to develop new solutions. Inevitably, markets and customers are expanding, while catalogues are getting richer.

Ambition and humility:

The One-Too methodology, through our quality management approaches undertaken throughout each project, allows us to strive for excellence. The know-how, the technical skills and the detailed knowledge of the markets are essential but cannot be sufficient for themselves.

One-Too is the solid balance between humility and ambition. It is a level of requirement that is based on privileged relationships with our clients and partners. They mix frankness, loyalty and confidentiality. The success of each project is a constant objective and can only be achieved through effective teamwork, sustained collaboration with customers and suppliers.

The eco-design:

Essential, eco-design approaches have been serving the sustainability of One-Too solutions for many years.

Engaging in sustainable development is not only a matter of course in terms of corporate social responsibility, but also a methodological imperative in terms of economic performance.

Eco-design is in tune with the times, but for One-Too it is above all a conviction. Developing sustainable solutions through respectful processes means working towards efficiency and sustainability.

For us, eco-design adheres to the precepts of always: to remove the superfluous and useless to keep the essential.
