Field of application
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
Device properties:
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
Benefits
Energy and cost savings for ventilation control due to very low zero offset and accurate measurement
Low operational costs because no air aspiration of ambient air and no test gases are required
Low maintenance requirements due to long maintenance interval (approx. 1 year)
