Our mission is to provide systems that enable operators to run their tunnels at financially efficient levels whilst protecting tunnel users from the irritating and dangerous effects of traffic pollution.

We offer a complete range of tunnel atmosphere monitoring sensors, designed for measuring visibility and dust, CO, NO, NO₂, air speed & direction as well as tunnel luminance and illuminance.

All Tunnel Sensors products are designed, assembled and tested at our premises in Oxfordshire, UK. With in-house product assembly, software design and R&D capabilities, the team has responsibility for all activities from design conception through to the final product. 

As a company with a firm foundation in electronic engineering, we have a flair for research and a track record of turning that research into powerful, marketable products. In this way we always retain the option to offer customised solutions to meet any specific customer requirements.

Furthermore, as an ISO9001:2015 accredited company our quality management system is continuously assessed for all elements of manufacture, supply, service.

In 2019 Tunnel Sensors and parent company Dynoptic Systems Ltd became part of the ACOEM Group. With Headquarters in France, ACOEM are a global leader in envrionmental monitoring helping companies and public authorities control and reduce their impact on the envrionment. 

ACOEM’s products and services enable customers to prevent noise and vibration pollution, improve air quality and increase the productivity and reliability of industrial machines.
