【 Model FT-SGT1 】 Fengtu Technology: A professional manufacturer, dedicated team, and fast response, creating a reliable backing in one. What are the core advantages of this portable instrument? Why adapt to long tunnels and multi section detection?

The core advantage is "portability+stability and reliability", which precisely meets the core requirements of long tunnels and multi section detection! Capable of providing one-stop solutions to the diverse needs of tunnel inspection; Portability "is reflected in the fact that it does not require installation and debugging, can be tested immediately when powered on, and is suitable for fast movement detection of multiple sections; At the same time, optimized design is carried out for the harsh environment inside the tunnel, ensuring secure and stable data storage. These advantages solve the problems of "inconvenient movement, complex parameters, and harsh environment" in long tunnel detection, making the detection work more efficient and accurate.

1、 Product Introduction

The SGT1 portable light transmittance detector does not require installation and debugging, and can be tested by powering on. The detection data is displayed in real-time on the LCD screen. Considering the harsh natural environment inside the tunnel, it is not convenient to synchronously connect to a laptop to store data. The instrument comes with its own internal memory, which can automatically save the detection data. After the detection is completed, the instrument is brought back to the laboratory and connected to a computer. The optical 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 access and use.

2、 Main purpose

The atmospheric light transmittance under various atmospheric environments, the visibility values of highways under various atmospheric environments, the acceptance detection values of VI and CO values in tunnels, and the temperature and humidity detection values in tunnel environments
