Smoke Optical Density Detector

Smoke optical density detector is one of our professional industrial instruments for measuring smoke opacity and optical density. Mainly deployed in road tunnels and industrial fire‑safety monitoring systems, this detector evaluates smoke diffusion status once fire breaks out. Adopting light‑beam attenuation measuring method, it obtains objective smoke density index. Mechanical structure is optimized for dusty, exhaust‑polluted tunnel environment, with anti‑dust protective window design to extend maintenance cycle. Digital output connects to tunnel fire‑alarm and ventilation control system. Strict factory calibration ensures measuring consistency. Engineering contractors and tunnel operation teams adopt this smoke optical density detector to support fire‑safety judgment for infrastructure facilities.
