MARKET SEGMENTATION

NOx gas sensor is expected to gain significant popularity in the global industrial gas sensors market

The NOx industrial gas sensors segment is expected to gain significant momentum in the global industrial gas sensor market as a result of increasing awareness regarding the impact of NOx emission on climate change. For instance, data from the NASA satellite stated gases detrimental to the atmosphere through made precision measurements on a daily basis, which heightens the importance of installing industrial gas sensors.

Thus, the observation predicted NOx emissions through various regions. The Middle East is expected to remain constant until 2030. Lebanon observed a fall in CO2 emission by 20% in 2011, but its NO2 emission increased by more than 20% in 2014. Thus, increasing environmental awareness through different studies is expected to result in the growth of NOx industrial gas sensors to monitor the emission levels around the world.

CO2 gas sensors, a vital type of industrial gas sensors, are expected to witnessed growth owing to the demand from various industry verticals such as food manufacturing, power plants, generators, boilers, and medical. This is attributed to the combustion of fossil fuel, including oil, gas, and coal. The increasing importance of personal health monitoring in the industrial sector has resulted in the rising adoption of CO2 industrial gas sensors to protect the employees, which will augment the global industrial gas sensors market revenue.

Furthermore, the increasing product development from various manufacturers is expected to drive the market in the near future. For instance, in 2017, the Gas Sensing Solutions (GSS), a UK based manufacturer launched a compact CO2 sensor with SmartIR LED technology.

The infrared technology is likely to observe the fastest growth in the market over the forecast period. This is attributed to the increasing demand for reliable, quick, maintenance-free, compact sensors, and varied types of gases. These industrial gas sensors are gaining popularity among various industries, including oil & gas, chemical, and petrochemicals, to avoid accidents.
