Nitrogen Dioxide Gas Detectors
Nitrogen dioxide (NO₂) is a toxic, reddish-brown gas with a sharp, acrid odour. It is one of a group of gases known as nitrogen oxides (NOx) and is a strong oxidising agent.
NO₂ is found in a wide range of environments. Outdoors, it is present near busy roads with high traffic density due to diesel and petrol engine exhaust emissions. In industrial settings, nitrogen dioxide may be present in power generation plants. It can also be generated in confined spaces where diesel-powered equipment is operating.
Exposure to nitrogen dioxide poses serious health risks. It primarily affects the respiratory system, irritating the lungs and airways. Short-term exposure to elevated concentrations can cause coughing, wheezing, shortness of breath, and chest tightness. Higher exposures may lead to inflammation of the lungs and, in severe cases, delayed-onset pulmonary oedema. Long-term exposure to lower concentrations has been linked to reduced lung function and increased susceptibility to respiratory infections.
The Blackline Safety G8 is a connected personal gas detector designed for real time monitoring. It provides continuous NO₂ monitoring and can transmit alerts and exposure data to a live monitoring platform, making it particularly suitable for lone workers.
The BW Solo is a compact, single-gas detector designed for personal protection. It is lightweight and offers reliable electrochemical sensing for toxic gases such as nitrogen dioxide. Its simple one button operation and clear display make it well suited for day to day use.
The Crowcon Xgard provides a robust and flexible solution. The Xgard is designed for permanent installation. It can be configured with appropriate sensors to detect nitrogen dioxide.

FAQs
Nitrogen dioxide (NO₂) is a toxic, reddish-brown gas with a sharp, irritating smell.
NO₂ is commonly found in areas with vehicle emissions, such as busy roads, tunnels, and car parks. In industrial settings, it may be present in boiler rooms, power plants, welding operations, metal processing facilities.
