Pioneering the industry

Four decades ago, DELTA RoadSensors was the first to introduce a retroreflectometer. Since then, DELTA has become part of FORCE Technology, and today, as a global leading supplier of retroreflectometers and the preferred choice of professionals, we continue to be a driving force in developing international standards on retroreflection measurement of pavement markings and road traffic signs.

In many countries, DELTA retroreflectometers have become the de-facto industry standards in use, helping ensure optimum driving conditions at night and thus reducing accidents and saving lives.

Trusted quality

A proven customer track record – not least by use in the industry and by road authorities in 65 countries and 6 continents – tells a story of its own. High performance, quality in measurements, and reliable instrumentation guarantee optimum solutions in measurements of retroreflectivity.

Close cooperation with customers and authorities

Users’ trust in our products is key in our instrument philosophy. We spend significant resources in ongoing verification and validation of our product range in close cooperation with selected customers and authorities – for instrument use in the field as well as in the lab. This insures a balanced and minimum cost of ownership for DELTA retroreflectometers – from simple handheld instruments to sophisticated mobile solutions.
