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
优势
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)
The Gas Adjustment Kit continuously checks the gas type and measuring
range set for agreement with gas type and measuring range of the
connected gas sensor and outputs an error if there is an inconsistency.
