Since 1982, the RSD technology has been successfully used all around the world

Opus RSDs have measured hundreds of millions of vehicles worldwide!

The use of our systems in Europe does not stop growing:

Opus RSE has brought RSD technology to many European countries, performing different types of projects and providing enormous benefits to its customers. Most uses of the RSD in Europe seek to monitor traffic emissions in cities, but they are also used in other applications, such as finding highly polluting vehicles, finding vehicles illegally tampered with by the police, or evaluating public or private bus fleets.

Besides, the use of RSD is not confined to Europe alone. For instance, programs of continuous emissions monitoring are giving very good results to many states of USA since decades.
