Gas Detection Equipment Market Forecast to Reach $15 Billion by 2031

The global market for gas analysers, sensors and detectors is forecast to grow from $11.35 billion in 2026 to $15.05 billion by 2031. The estimate implies average annual growth of 5.8 per cent.

The growth is being driven by industrial safety requirements, process monitoring and tighter emissions controls.

For maintenance organisations, the market trend reflects a wider shift towards continuous condition and safety monitoring. Demand is increasing for equipment that can detect toxic and combustible gases in real time, respond quickly and monitor several gases simultaneously.

The oil, gas and chemical industries are expected to be the fastest-growing end-use segment between 2026 and 2031, with projected annual growth of 7 per cent. New LNG and hydrogen infrastructure, carbon-capture plants and petrochemical investments are expanding the number of sites that require gas detection and analysis.

Methane and volatile organic compound emissions rules are also increasing demand for monitoring equipment. In addition to workplace safety, gas sensors are becoming more important in environmental compliance and process control.

Portable systems accounted for the largest share of the market in 2025, at 66.4 per cent by value. Gas analysers represented 47.1 per cent of the market, while electrochemical technology was the largest individual sensor technology segment.

Asia Pacific was the largest regional market in 2025, supported by industrial expansion and investment in manufacturing, energy infrastructure and environmental monitoring. Demand in Europe and North America is being supported by stricter safety and emissions requirements, industrial modernisation and wider use of digital monitoring systems.

Future growth is expected to depend increasingly on wireless sensors, connected monitoring systems, smaller devices and analytics based on artificial intelligence.

Market forecasts are estimates rather than observed sales, but they point to a growing role for gas-monitoring equipment in both maintenance and operational safety.
