In tunnels, air quality and safety depend on measuring well and continuously. dnota offers equipment to monitor gases, opacity, particles and airflow in road tunnels and other underground environments.
Gas detectors
Optical gas detectors to identify leaks or abnormal concentrations of carbon monoxide (CO) and nitrogen dioxide (NO2) in road tunnels and industrial environments.
- Carbon monoxide (CO) detector
- Gas detector carbon monoxide CO
- Optical nitrogen dioxide (NO2) detector
- Nitrogen dioxide gas detector NO2
Opacimeters
Continuous optical monitoring of air opacity along the tunnel.
Ultrasonic anemometers
Measurement of airflow speed and direction in tunnels.
Ultrafine particles
Analyzer for industrial and transport environments, such as tunnels and mining.
