Tunnel Covi Detection Instrument (Tunnel VICO 100)

1. Product Overview of Tunnel Covi Detector

The tunnel is a special tubular structure. Due to its small space and airtight characteristics, if the exhaust gas emitted by vehicles passing through the tunnel is not discharged in a timely and reasonable manner, it will cause toxic gases such as carbon monoxide (CO) to exceed the standard and cause suspension. The accumulation of particulate matter reduces visibility (VI), which will directly affect personal safety and driving safety. By monitoring the VI and CO conditions in the tunnel around the clock, fans can be started in time for forced ventilation to ensure driving safety. 

ASHUR Tunnel VICO 100 tunnel covi detector, also known as "COVI detector" and "tunnel smoke concentration/carbon monoxide detector", uses optical principles to detect, and can collect visibility (VI), carbon monoxide (CO) and other data in the tunnel online, and can Expand the monitoring of harmful gases such as NOX, CH4, H2S, SO2, etc. to meet the requirements of the "Road Tunnel Ventilation and Lighting Design Code" and provide decision-making basis for tunnel ventilation and safe road traffic.
