Tunnel sensors 
On the road to developing active traffic safety.
More safety, less congestion – this is the main objective of traffic management in the future. Intelligent traffic monitoring systems will form the basis of modern traffic management technology. With our highly sophisticated measuring systems, we’re on the right road to solving a few of these issues.
 
As the volume of traffic rises, the need to continuously monitor pollution levels is becoming increasingly important. Our in-situ monitors measure exhaust gases where they arise, thereby enabling effective monitoring and control of emissions, and ensuring that ventilation systems operate efficiently. Developed by experts with many years of experience, our measuring systems are tailored to meet your requirements.
