Incident Response at Central-Wan Chai Bypass Tunnel with Comprehensive Air Quality Monitoring in Hong Kong

In response to a ventilation system malfunction at Tunnel East Ventilation Building in Hong Kong, Sapiens rapidly deployed multiple autonomous MAD-AF300 monitoring stations to provide real-time air quality data focused on oxides of nitrogen and PM for the tunnel and surrounding areas. This monitoring data supplemented the Highway Department’s investigation, helping to assess the environmental impact and formulate emergency response solutions.

MAS-AF300

MAS-AF300 is the flagship model of Sapiens Mini Air Station (MAS) series products for high performance and long-term outdoor air quality monitoring with integrated autonomous data quality control capabilities. The product can measure criteria air pollutants including particulate matters (PM₁, PM₂.₅, PM₁₀, TSP), nitrogen dioxide (NO₂), ozone (O₃), carbon monoxide (CO), sulfur dioxide (SO₂) and nitric oxide (NO) with near reference data quality under all weather conditions.
