50 PPM Range
Prana Air NO2 sensor operates on this electrochemical gas sensing mechanism. The accurate Prana Air sensors have been employed in numerous research projects. When it comes to long-term continuous monitoring, our products are renowned for being dependable and durable. These sensors are built to withstand tough conditions both indoors and outside for a long time.
NO2 gas typically enters the atmosphere as a result of fuel combustion, such as emissions from vehicles including cars, buses, trucks, and factories. Its airborne presence aids in the formation of air pollutants. This gas is extremely dangerous and can lead to respiratory illnesses, asthma attacks, and even lower crop yields in agricultural operations.
The sensor has a robust signal, low zero current resolution of 50 parts per billion (ppb), and a 20ppm operational range. It works well with portable, fixed, gas analyzer, and air quality monitoring equipment. The sensor features dependable long-term detection performance and a warranty against electrolyte leaks.

The atmospheric pollutant nitrogen dioxide has a strong smell. Reddish-brown, brown, or yellow are the colours of gas. The gas reacts with combustible and reduceable materials because of its high degree of oxidation. Nitric acid and nitric oxide may be produced as a result of the process. Fossil fuel combustion, vehicle emissions, explosive use, welding, the refining of metal and petroleum, volcanoes, and microbiological activity are some of the sources of nitrogen dioxide.
The sensor is small in size having ultra-thin packaging that eases the fit in big and handheld devices for monitoring.
The sensor has about 10 years (a decade) of operational life outlasting other sensors available on the market.
The sensor has a swift response time of about 15 seconds.
The power input required by the nitrogen gas sensors for operation is very low which reduces the energy consumption.
For higher accuracy and precision, the sensor is individually calibrated.
The nitrogen Dioxide sensor is free from toxic and hazardous substances and is in compliance with ROHS.
The electrochemical gas sensing technique is the foundation for the nitrogen dioxide gas sensors. Oxidation and reduction are the foundation of the technology. Every time gas travels over the sensor, current is produced between the working and counter electrodes. An ion conductor connects the working and counter electrodes. The nitrogen dioxide concentration in the air is determined by the generated current. This technique for calculating NO2 concentration has been demonstrated to be reliable and accurate.
The sensor is calibrated in a standard environment with the following parameters: 23 + 3 °C temperature, 50 + 15% relative humidity, 0.9-1.1 atm pressure, and 0.05 m/s air velocity. Calibration is the process of comparing a reference measurement to an observed measurement made with your equipment. Nitrogen dioxide is present in an area of interest, and a NIST standard gas cylinder is employed as a calibration reference.
