Tunnel NOx detector (Tunnel NOx)

1. Product Overview of Tunnel Nitrogen Oxide Detector

The tunnel is a special tubular structure. Due to its small space and airtight characteristics, if the exhaust gases emitted by vehicles passing through the tunnel are not discharged in a timely and reasonable manner, it will cause toxic gases such as nitrogen oxides (NOX) to exceed the standard. Directly affects personal safety and driving safety. By monitoring the NOX value in the tunnel around the clock, fans can be started in time for forced ventilation to ensure driving safety. ASHUR Tunnel NOX tunnel nitrogen oxide detector can collect NOX values in the tunnel online, meeting the requirements of the "Road Tunnel Ventilation and Lighting Design Specification" and providing a decision-making basis for tunnel ventilation and road safety.

2. Product Functions of Tunnel Nitrogen Oxide Detector

●Can continuously measure the content of NO, NO2 and other gases in the tunnel online;
