Tunnel visibility monitor

1.Tunnel visibility monitor product introduction

Tunnel visibility monitor measures the light transmission rate in the atmospheric optical channel to reflect the light transmission rate, so as to obtain tunnel visibility and smoke concentration.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
