Tunnel gas monitor

1.Tunnel gas monitor Product Overview

Tunnel gas monitor is a safety device used in roads, railways, and construction tunnels to measure harmful air pollutants and toxic gases.Tunnels are special tubular structures. Due to their small size and enclosed nature, vehicles passing through tunnels emit large amounts of toxic and harmful gases. If these gases are not promptly and properly released, they can exceed safe levels, potentially seriously endangering the safety of personnel and vehicles within the tunnel. Tunnel gas monitor is a gas environment monitoring device specifically designed for tunnel environments. It can accurately and in real-time detect the concentrations of various harmful and flammable gases within tunnels, including but not limited to methane (CH₄), carbon monoxide (CO), carbon dioxide (CO₂), hydrogen sulfide (H₂S), nitrogen dioxide (NO₂), and nitric oxide (NO), as well as monitor temperature and humidity within the tunnel. By monitoring the concentrations of toxic and harmful gases within the tunnel around the clock, forced ventilation can be activated promptly to ensure driving safety. The tunnel multi-gas detector adopts a high-sensitivity sensor and a waterproof housing design to collect online concentration values of toxic and harmful gases and combustible gases in tunnels. It meets the requirements of the "Specifications for Ventilation and Lighting Design of Highway Tunnels" and can operate stably under harsh tunnel conditions. It provides reliable data support for tunnel construction, operation and emergency response, and reduces the hazards of toxic gases in tunnels.
