The Opus Remote Sensing Device (RSD) is a sensor that measures the actual emissions of each vehicle under real traffic conditions, remotely and automatically.

The company offers the world's only ISO 17025-accredited solution for this application.

The device remotely measures exhaust emissions from road vehicles as they are driven past the system, casting a narrow and invisible beam of light across the road and through the trailing exhaust. The system also incorporates a video camera to identify the license plate of the vehicle and link its real emissions.

The system automatically records for each vehicle:

• Real exhaust emissions: CO, NO, NO2 (NOx), HC, PM2.5 and NH3
• Speed and acceleration (and estimates vehicle specific power)
• Ambient conditions: temperature, pressure, humidity
