Our diversified product portfolio covers industrial & residential gas detection & alarm systems, industrial & household gas solenoid valves, and urban gas pipeline network monitoring systems—all engineered to adapt to complex working environments and strict safety requirements. We produce and sell tens of millions of units annually, catering to a wide range of industries that demand reliable gas detection solutions, including oil & gas exploration and production, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, new energy, steel production, and beverage processing.
Guided by the core mission of “Making Gas Safety Accessible Everywhere,” we consistently deliver high-performance, reliable products and customized solutions tailored to each client’s unique needs. Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications, including national compulsory Products Certification, explosion-proof certification, fire product certification, CPA measurement instrument type approval certificate, and international approvals as CE, SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise", "National Quality Leading Enterprise in the Gas Alarm Industry," member of the China Fire Protection Association, and the main drafting organization for the national standard of solenoid valves, further confirming its industry influence and reputation.
In the field of intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. These patents cover core technological areas, including a graphical monitoring system for gas detection and alarm, which enables predictive maintenance based on historical data to reduce equipment failure rates by over 30%, and a solenoid valve with flow monitoring functionality that integrates flow detection and alarm capabilities. The company also pioneered China's first networked bus-type gas leakage monitoring system and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security, demonstrating its leading position in cutting-edge technological research.
Our in-house laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. It operates in accordance with ISO/IEC 17025, the international standard for testing and calibration laboratories. It provides reliable and traceable testing services for gas detection and alarm products, solenoid valves, and related safety equipment. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities, certification bodies, and customers in China and overseas, helping to ensure product quality, safety compliance, and market access.
Combining world-class automation with rigorous lean manufacturing principles to deliver scalable, reliable ODM and OEM systems.
Our surface mount technology lines minimize human error, ensuring repeatable solder joints and flawless circuit performance for volatile environments.
Utilizing Kanban systems and flexible assembly configurations, we transition seamlessly from high-volume orders to tailored, low-batch custom gas monitor requests.
Every single gas sensor and solenoid valve is stamped with a unique laser-etched ID, tracking its component origin, testing sequence, and quality sign-off.
Designing for the next generation of hazard detection: Smart IoT networks, edge computing, and sensor-fusion diagnostics.
As the industrial sector transitions toward Industry 4.0, gas safety devices are evolving from passive alarm sounders into proactive, data-rich environmental intelligence nodes. Our roadmap focuses heavily on implementing advanced sensor-fusion architectures that combine electrochemical, catalytic, and infrared sensors in single micro-modules to eliminate false alarms and extend operational lifetimes.
Simultaneously, our R&D division is finalizing integration protocols for sub-GHz long-range communication grids. This technology allows gas detectors to construct low-power mesh networks covering complex pipeline matrices or sprawling chemical yards without the prohibitive cost of physical cabling.
Embedding predictive models directly inside our emergency shut-off valves to detect abnormal flow signatures before leaks physically occur.
Expanding the Xinhaosi IoT Suite to support real-time fleet health metrics, sensor drift warnings, and compliance logging tools.
Working closely with worldwide semiconductor fabs to prototype solid-state gas sensors with operational lifespans exceeding 8 years.
Custom-engineered safety ecosystems adapted to volatile operations, hazardous manufacturing, and high-density residential grids.
Our heavy-duty, explosion-proof ATEX/IECEx gas transmitters stand up to corrosive atmospheres, monitoring hydrogen sulfide, methane, and oxygen deficiencies on processing platforms.
Real-time pressure drop sensors and automated solenoid safety valves form a defensive perimeter, stopping fuel leaks at distribution hubs before they enter urban mains.
Engineered for high-density, multi-tenant properties. Certified methane and carbon monoxide alarms integrate directly with smart shutoff valves, protecting millions of homes annually.
Managing global gas safety procurement requires a deep analysis of total cost of ownership (TCO), supply chain resilience, and long-term regulatory compliance. Beyond initial hardware costs, technical buyers prioritize long calibration cycles, low sensor failure rates, and easy in-field maintenance to keep operational expenses low.
Our OEM/ODM workflow is structured to address these exact metrics. We offer complete transparency on Mean Time Between Failures (MTBF) data, component material traceability, and environmental ESG compliance profiles. This ensures that large-scale infrastructure projects meet internal engineering audits, environmental safety regulations, and financial performance goals.
Operating gas safety systems globally requires meeting diverse local regulations and standards. Whether you need CE and SIL2 certifications for Europe, or specialized country-specific measurement approvals, our compliance team ensures your equipment meets all necessary requirements.
To support global deployments, we provide comprehensive multilingual technical documentation, regional calibration procedures, and round-the-clock technical assistance. This local support helps our partners minimize commissioning delays, pass strict safety audits, and confidently manage safety critical systems.
