Description
The QEL Q5-NO2-10P-0-A is a professional-grade Nitrogen Dioxide (NO2) gas detection sensor engineered for demanding commercial and industrial HVAC applications. Nitrogen dioxide is a toxic combustion byproduct commonly found in parking garages, mechanical rooms, boiler plants, and other facilities where fossil-fuel combustion equipment operates. Accurate, continuous NO2 monitoring is essential for occupant safety, code compliance, and proper ventilation control.
Key Features
- Designed to detect Nitrogen Dioxide (NO2) — a hazardous combustion byproduct

- Analog output signal for seamless compatibility with controllers and DDC systems
- Suitable for commercial and industrial environments including parking garages, boiler rooms, and mechanical spaces
- Compact, durable sensor housing for reliable long-term deployment
- Supports demand-controlled ventilation (DCV) strategies to optimize energy efficiency
- Part of the QEL Q5 series gas detection platform
Applications
- Parking garages and loading docks
- Boiler rooms and mechanical equipment rooms
- Commercial kitchens and industrial facilities
- Building automation and demand-controlled ventilation systems
- Indoor air quality monitoring programs
Why NO2 Detection Matters
Nitrogen dioxide is produced by the combustion of natural gas, diesel, and other fossil fuels. Even at low concentrations, prolonged NO2 exposure poses serious health risks. Deploying a dedicated NO2 sensor like the Q5-NO2-10P-0-A enables your building automation system to trigger ventilation responses automatically — protecting occupants and helping meet ASHRAE and local code requirements.
