Met One Instruments, Inc. Air Quality Products for Tunnels
Protect Commuter & Employee Health with Reliable Sensors
Subway systems in America typically shuttle millions of people each day.
Recent studies, however, have found levels of PM2.5 air pollution to be alarmingly high in these underground transportation networks. Tunnels are restricted and confined, often with poor ventilation, making them naturally susceptible to air quality issues. Elevated levels of suspended PM2.5 air particulate can lead to respiratory conditions, lung cancer, and heart disease for commuters and employees.
Met One Instruments, Inc. offers several candidate products to measure air velocity, temperature and humidity, and particulate concentrations for tunnel monitoring. We also provide OEM particulate count and particle mass engines that integrate with comprehensive tunnel air monitoring and air handling systems. Sense and respond with confidence with Met One’s tunnel monitoring instrumentation.
