1.Tunnel visibility monitor product introduction
Tunnel visibility monitor is an efficient and portable device used to measure road visibility and smoke concentration in tunnels.Tunnel visibility monitor does not require installation and debugging. It can be tested after powering on. The LCD screen displays the test data in real time. Considering the harsh natural environment in the tunnel, it is not convenient to connect to a laptop to store data. The instrument has its own internal memory, which can automatically save the test data. After the test is completed, the instrument is brought back to the laboratory and connected to the computer. The light transmittance display software can automatically import the data saved in the internal memory of the instrument into the computer and save it in EXCEL format for customers to review and use.
2. Main uses of tunnel visibility monitor
Atmospheric light transmittance under various atmospheric environments
Visibility values of highways under various atmospheric conditions
Acceptance test values for VI and CO values in tunnels
Temperature and humidity test values in the tunnel environment
