1. Product introduction of portable light transmittance detector

The portable light transmittance detector is also called the portable atmospheric light transmittance detector. The portable light transmittance detector does not require installation and debugging. It can detect when the power is turned on. The detection data is displayed in real time on the LCD screen, taking into account the harsh natural environment in the tunnel. , it is not convenient to connect to a laptop to store data simultaneously. The instrument has its own memory, which can automatically save the test data. After the test is completed, take the instrument back to the laboratory and connect it to the computer. The light transmittance display software can automatically save the data inside the instrument. The data saved on the memory is imported into the computer and saved in EXCEL format for easy reference by customers.

2. Main uses of portable light transmittance detector

Atmospheric light transmittance under various atmospheric environments

Visibility values of highways under various atmospheric environments

Acceptance testing values of VI and CO values in tunnels

Temperature and humidity detection values of the tunnel environment
