The VICOTEC410 product family of compact analyzers provide measurement values for visibility or carbon monoxide concentrations in road tunnels:
| VICOTEC411 for measurement of visibility |
| VICOTEC412 for determination of CO concentrations |
| VICOTEC414 for the simultaneous measurement of visibility and CO concentrations. |
These measurement devices request maintenance only when sensors are contaminated - reducing maintenance costs to a minimum. The VICOTEC411 monitors visibility in a tunnel and thus provides continuous information on visibility conditions. A continuous, real-time control signal is used for optimizing the ventilator efficiency. The VICOTEC412 monitors CO pollution within the tunnel atmosphere. The VICOTEC414 offers combined measurements for simultaneous monitoring of visibility and CO concentrations.
