Tunnel Sensors - A network
of local distributors worldwide

Tunnel Sensors is a global leader in the design and manufacture of speciality sensors for tunnel atmosphere monitoring. We design and manufacture our own analysers specifically for pollution monitoring in the traffic tunnel environment.

We bring fresh ideas and technology to a sector that has traditionally used systems adapted from exhaust stack and chimney monitors. Our analysers are designed to be combined in a modular fashion, offering the flexibility to create monitoring systems specifically adapted to the requirements of individual tunnels. Because tunnels throughout the world have diverse requirements for data presentation, our systems also offer a flexible output and communication system that allows seamless integration with any existing tunnel system or bus.

Tunnel Sensors instruments are installed in more than 30 countries wordwide with references in:

Asia | Europe | Middle East | Americas | Oceania | Africa
