1. Overview
The CO/VI expandable multi-gas detector is designed for on-line data collection of VI, CO, CO₂, NO, NO₂, H₂S, CH₄, etc., in tunnels.It provides a reliable basis for tunnel ventilation and road traffic control, and can real-time monitor multiple gas concentrations, visibility, air temperature and humidity inside the tunnel.
The measurement of CO, CO₂, NO, NO₂, H₂S and CH₄ adopts infrared principle and electrochemical principle.Visibility measurement uses the infrared scattering principle, measuring visibility by detecting light wave attenuation.Air temperature and humidity are measured by gap-type and capacitive sensing principles.
It is suitable for emission control and filter control, ensuring optimal air quality in tunnels.
