PRODUCT DESCRIPTION
Tunnels are enclosed, tubular structures with limited space and restricted ventilation. Exhaust emissions from vehicles traveling through tunnels, if not effectively discharged, can lead to the accumulation of carbon monoxide (CO) and suspended particulate matter, posing serious risks to drivers, passengers, and maintenance personnel.
To ensure safety, continuous monitoring of visibility (VI) and carbon monoxide (CO) concentration inside tunnels is essential. This enables timely activation of ventilation systems, such as jet fans, and the implementation of other control measures.
The YG-JTDL13 Tunnel COVI Detector provides 24/7 real-time monitoring of tunnel environmental conditions, making it an indispensable device in modern intelligent transportation systems for enhancing tunnel safety and operational efficiency.
