2. Product Overview

Tunnels, as specialized tubular structures, present unique challenges due to their confined spaces and lack of natural ventilation. If exhaust emissions from vehicles are not managed effectively, they can lead to elevated levels of toxic gases, such as carbon monoxide (CO), and reduced visibility (VI) caused by the accumulation of suspended particulate matter. These conditions pose significant risks to both personal and driving safety. Continuous monitoring of VI and CO within tunnels is essential to ensure timely activation of ventilation systems, thereby maintaining safe driving conditions. ASHUR Tunnel VICO 100 Tunnel VI/CO Monitoring Instrument, commonly referred to as the "CO VI detector," employs optical principles to detect and collect real-time data on tunnel visibility and carbon monoxide levels. Additionally, it can monitor other harmful gases, including NOX, CH4, H2S, and SO2, fully complying with highway tunnel ventilation and lighting design specifications. This comprehensive monitoring providing a decision-making basis for tunnel ventilation and road safety passage.

3. Product Function

●Online continuously measuring visibility (VI) and carbon monoxide (CO) in the tunnel; extended monitoring harmful gases such as NOX, CH4, H2S, SO2;

●The digital output interface of the instrument is RS-232 or RS-485, and the analog output interface is 4-20 mA;

●Instrument built-in ModBus protocol, facilitate the tunnel network monitoring application;
