A tunnel visibility sensor is a device used to measure visibility data in tunnels and is one of the main tools used to monitor and improve traffic safety in road tunnels.
Tunnel visibility sensors measure visibility in the air primarily through the use of a laser beam. By measuring the scattering and absorption of dust particles, it is possible to quickly and accurately measure COVI data in tunnels and provide instant feedback to the user.
This sensor has the following advantages -
High accuracy: The Tunnel Visibility Sensor uses advanced technology with high accuracy and sensitivity to quickly and accurately measure the concentration of fine particles in the air.
Real-time monitoring: The Tunnel Visibility Sensor is capable of monitoring air quality in tunnels in real time and can continuously monitor data from multiple tunnels in order to keep abreast of changes and trends in air quality and pollution levels.
Easy to install and maintain: Tunnel visibility sensors are typically small and lightweight, making them easy to install and maintain. They also feature automatic calibration and fault status feedback to ensure accuracy and stability.
Versatility: Tunnel visibility sensors are often capable of monitoring different types of items simultaneously, including visibility (VI) and carbon monoxide (CO).
Easy data processing: modern tunnel visibility sensors are equipped with specialised software that processes and analyses the measurement data to produce visual data reports. The software enables the user to easily manage multiple monitoring points, analyse and compare data.
Tunnel visibility sensors are widely used in road tunnels, railway tunnels, underground tunnels and other tunnelling projects, to understand the air quality conditions in tunnels in a timely manner, to provide a scientific basis for the safe management of transport, to reduce the impact of haze on human health, and to ensure the safety of transport and smooth flow.

Dissolved oxygen refers to molecular oxygen dissolved in water, usually denoted as DO, with the unit of mg/L. It is essential for the survival of aquatic organisms. If the concentration drops below 4 mg/L, fish may suffocate to death. When it is lower than 2 mg/L, the water body enters an anaerobic...
