Transmissometer

Transmissometer is high‑performance traffic environment sensors applied for high‑precision visibility measuring in tunnel and highway scenarios. Based on light‑transmittance detecting principle, this transmissometer achieves higher‑accuracy visibility measurement compared with scattering‑style sensors. In tunnel projects, it monitors atmospheric visibility for fire‑smoke assessment and ventilation control. Along expressways, it provides reliable fog‑condition data for traffic early‑warning. Firm installation structure resists vibration and exhaust contamination. It outputs standard digital signal to dock with traffic monitoring host. Tunnel operators and highway management departments trust our transmissometer for critical visibility‑safety monitoring tasks.
