Founded in 2003, Xinhaosi has spent more than twenty years building a reputation as one of the global gas safety industry's most trusted manufacturers and OEM partners. Integrating state-of-the-art Research & Development, highly automated smart manufacturing, comprehensive global supply networks, and a dedicated team of engineers, we provide life-saving gas safety technologies worldwide.
Our footprint extends across two massive manufacturing facilities: our core Chengdu Office & Factory and our newly developed Deyang Production Base. Together, these facilities manufacture tens of millions of gas alarms, intelligent solenoid valves, and network control devices annually, ensuring reliable safety installations for clients across heavy industrial sectors, municipal networks, and millions of residential homes.
Our mission, "Making Gas Safety Accessible Everywhere," guides us to construct highly resilient sensing devices engineered to withstand extreme climates, chemical interference, and rigorous usage scenarios.

Advanced Deyang Intelligent Production Base
As global energy systems transition to mitigate methane slip and fugitive emissions, Xinhaosi helps industrial enterprises build compliant, automated monitoring networks. We specialize in custom OEM and ODM configurations, tailoring sensor selection, enclosure designs, communications (Modbus, LoRa, NB-IoT), and safety certifications to specific regional market demands.
Xinhaosi operates under strict adherence to the ISO9001 Quality Management System, securing certifications including National Compulsory Product Certification (CCC), ATEX/IECEx explosion-proof certifications, and SIL (Safety Integrity Level) ratings.
Our in-house calibration lab is accredited by the China National Accreditation Service (CNAS) and recognized globally under the ILAC-MRA framework, operating under ISO/IEC 17025. This ensures that every gas sensor calibrated at our facility is fully traceable to international reference standards, simplifying import, compliance, and field deployment processes for international markets.
We hold over 50 patents and copyrights, including pioneering developments in network bus-type gas leakage monitoring systems and custom gas solenoid valves featuring integrated flow monitoring.

Comparing the core technologies used in methane sensing and outlining our long-term R&D roadmap.
Principles: Measures the heat generated when methane oxidizes on a catalytic pellistor bead. Used for detecting 0–100% LEL (Lower Explosive Limit).
Pros & Cons: Cost-effective, robust, and highly responsive. Susceptible to sensor poisoning from silicones, lead, or sulfur compounds over time.
Principles: Uses gas-specific infrared absorption characteristics (typically at 3.3μm or 7.7μm) to measure concentration without physical contact.
Pros & Cons: Immune to chemical poisoning, long operational lifespan (>10 years), and operates in oxygen-depleted atmospheres. Higher upfront cost.
Principles: Tunable Diode Laser Absorption Spectroscopy targets a specific methane absorption line, eliminating cross-sensitivity to other gases.
Pros & Cons: Extreme precision, ppm-level sensitivity, and long-range measurement. Typically reserved for specialized open-path and pipeline leak mapping.
Xinhaosi's R&D efforts focus on integrating intelligent edge diagnostics, low-power IoT protocols, and hybrid sensor configurations.
How our OEM methane detection systems are deployed across diverse industries and localized to meet strict regulatory safety standards.
Fugitive methane emissions pose significant safety risks and environmental challenges across upstream, midstream, and downstream infrastructure.
Our Solution: Explosion-proof, SIL2-certified detectors like the GTYQ-XP4000 and XP3000 series. Built with heavy-duty cast aluminum or stainless steel housings, these units resist corrosion and operate reliably in hazardous Class I Division 1 (Zone 1 and 2) atmospheres.
Urban gas grids require continuous monitoring at distribution stations, regulator pits, and valve chambers where leaked gas can pool undetected.
Our Solution: Low-power wireless gas detectors paired with high-performance controllers like the JB-TB-AT2020. These systems interface with safety shutoff valves (e.g., the XF3III Solenoid Valve) to automatically isolate leaks before they reach explosive limits.
High-density housing and commercial kitchens require reliable, low-maintenance gas alarms that minimize false triggers from cooking vapors.
Our Solution: The JT-AT3068 and JT-AT2013A residential detector series feature pre-calibrated, hot-swappable sensor modules, loud acoustic alarms, and direct relays to trigger home shutoff valves.
Steel manufacturing, automotive painting, chemical processing, and wastewater facilities often involve co-existing toxic and combustible gases.
Our Solution: Multi-gas platforms like the XP4000P track toxic gases, oxygen displacement, and volatile organic compounds (VOCs) on a single, unified bus network.
Ensuring consistent production capacity, high-speed delivery, and flexible customization for global safety equipment providers.
We control the entire manufacturing process, from raw PCB assembly on high-speed SMT lines to sensor encapsulation. This integration minimizes reliance on external component suppliers and keeps production schedules on track.
Our automated gas calibration chambers expose thousands of sensors simultaneously to precise gas mixtures under controlled temperatures, eliminating the manual calibration errors common with smaller factories.
We support custom housing designs, private-label branding, customized firmware, and regional communication protocols (such as Modbus RTU, BACnet, or LoRaWAN), helping clients bring products to market quickly.
