1.Introduction to Tunnel visibility monitor
Tunnel visibility monitor is a meteorological visibility monitoring device that can monitor visibility, CO concentration, ambient temperature and humidity in tunnels.Tunnel visibility monitor does not require installation and debugging, it can be detected by power on, and the detection data is displayed in real time on the LCD screen.Considering the harsh natural environment in the tunnel, it is not convenient to connect to the laptop to store data synchronously.The instrument comes with its own memory, which can automatically save the detection data.After the detection is completed, the instrument is brought back to the laboratory and connected to the computer.Through the light transmittance display software, the data saved on the instrument's internal memory can be automatically imported into the computer and saved in EXCEL format for customers to review and use.
2.Main uses of Tunnel visibility monitor
Atmospheric light transmittance in various atmospheric environments
Visibility values of roads in various atmospheric environments
Acceptance and detection values of VI and CO values in the tunnel
Temperature and humidity detection values of the environment in the tunnel
