GASTEC Launches Safer Catalytic Gas Sensor for Industrial Use

GASTEC Launches Safer Catalytic Gas Sensor for Industrial Use

2026-05-21

In industrial settings such as petrochemical plants, mines, or any environment with potential combustible gas leaks, a reliable and sensitive "safety guardian" is critical. Japanese manufacturer GASTEC has addressed this need with its newly released FG-3AL catalytic combustion-type combustible gas sensor, designed to safeguard industrial operations.

Compact Design with High Performance

The FG-3AL sensor measures just 33 x 30 x 36 millimeters and weighs only 30 grams. Despite its compact size, the device delivers exceptional performance, enabling rapid and accurate detection of combustible gas concentrations in the air. Its small form factor allows for easy integration into various gas detection systems without adding bulk.

Advanced Catalytic Combustion Technology

At the core of the FG-3AL sensor is catalytic combustion technology. This method utilizes specialized catalysts to facilitate flameless combustion of combustible gases on the sensor's surface. The resulting temperature change is measured to precisely calculate gas concentrations. The technology offers high sensitivity, fast response times, and strong resistance to interference, ensuring reliable operation in complex industrial environments.

Broad Industrial Applications

The FG-3AL sensor is suitable for multiple industries, including:

  • Petrochemical: Detecting leaks of methane, ethane, propane, and other combustible gases in refineries and chemical plants to prevent explosions.
  • Mining: Monitoring methane levels in coal and metal mines to protect workers.
  • Gas Supply: Identifying leaks in pipelines and appliances to avoid accidents.
  • Environmental Monitoring: Measuring methane emissions in landfills and wastewater treatment facilities.

Portable Detection Solutions

GASTEC also offers the MA-2510 handheld combustible gas detector, which incorporates the FG-3AL sensor for field use. The device features simple operation, portability, and precise measurements. For low-concentration gas detection, the MA-0510 model is also available.

GASTEC, a longstanding expert in gas detection technology, continues to innovate with products like the FG-3AL sensor. The company remains committed to enhancing workplace safety through advanced detection solutions.
