Field of application
Endress Hauser’s
The VICOTEC320 measures very small concentrations of NO2 and NO as well as the visibility and temperature in road tunnels quickly and simultaneously. And all this using industry-proven components – without test gases for zero and reference point. An automated, cyclic adjustment of zero and reference point ensures exact values. The rugged housing even withstands thorough tunnel washing operations without any impairments.
• Ventilation control and filter monitoring in tunnels
• Monitoring of air quality in road tunnels
• Very low detection limits for NO and NO2
• Automatic function monitoring and self-adjustment
• Very rugged design in stainless steel
• Automatic beam alignment between sender/receiver unit and reflector
