VICOTEC320 – Air Quality Tunnel Sensors

For the control of ventilation and for filter monitoring in road tunnels

The VICOTEC320 measures very small concentrations of NO2 and NO as well as the visibility and temperature in road tunnels simultaneously and quickly. 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 problems.

Description

The VICOTEC320 can be optionally equipped with an electrochemical CO measurement cell. This is useful for performing the plausibility checks which some tunnel standards (e.g., German RABT2006) recommend – even when NO2 is used as lead gas component.

At a glance
  • 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
Your 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)
