In industrial operation in oil and gas facilities, chemical plants, or coal mines, explosive gases or combustion gases are often present. In such hazardous environments, any electrical equipment, including gas sensors, must meet stringent safety requirements to prevent the risk of explosion. Many international regulations including ATEX and IECEx，mandate the application of certified equipment in explosive atmospheres，requiring the a high level of design integrity of sensor product in terms of structure, circuitry, and reliability, to ensure safe, compliant, and stable operation even under harsh conditions.
To meet the safety requirement of product operation under explosive environments, Cubic, a leading manufacturer of gas sensors and analyzers, proudly announces that its self-developed TDLAS methane sensor Gasboard-2501 has successfully achieved international explosion-proof certifications, including IECEx marking: Ex ia op is IIC T4 Ga and ATEX marking: II 1 G Ex ia IIC T4 Ga. Additionally, the laser component is safety-rated under the IEC 60825-1:2014 laser safety standard. With these certifications, Cubic TDLAS methane sensor Gasboard-2501 is qualified for methane detection that applied in virtually all hazardous areas—excluding underground mines—including Zone 0, Zone 1, Zone 2, and Class I Division 1 and Division 2 environments.
Cubic Gasboard-2501 is developed based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology and is engineered with a modular tunable laser source, optimized gas chamber, and precision optical path, which ensures exceptional accuracy, stability, and selectivity in methane detection. Designed with narrow absorption spectrum, Gasboard-2501 is immune to interference from humidity, CO2, ethane, or other gases. It delivers a measurement accuracy of ±5% LEL within a 0–100% LEL range, with no false positives or negatives, and provides ultra-fast response, enabling real-time detection of methane leaks. Its modular laser design also ensures zero-drift and long-term stability, significantly reducing the need for regular recalibration or maintenance.
By obtaining internationally recognized explosion-proof certification, Cubic reinforces its commitment to safety and innovation. Cubic Gasboard-2501 provides a reliable, high-performance solution for methane monitoring across critical sectors including oil & gas, energy, landfills, sewage treatment plants, refineries, LNG transport, fuel storage, pipeline leak detection, and greenhouse gas emissions monitoring.
