SICK Air quality measuring devices VICOTEC320

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.

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