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 internatinal 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.

Our research and development roadmap focuses heavily on Edge Computing and Artificial Intelligence integration. By transitioning from static threshold sensing to dynamic algorithmic prediction, our next-generation gas leak detectors analyze micro-fluctuations in gas density, eliminating false alarms caused by environmental humidity and pressure variations while ensuring millisecond response times in critical infrastructure.
Leveraging our dual-manufacturing ecosystem across Chengdu and Deyang, we integrate advanced automated surface-mount technology (SMT) lines, robotic calibration chambers, and ERP-driven inventory management. This digital transformation guarantees unmatched supply chain resilience, high-volume scalability, and strict cost-efficiency for international procurement partners.
Navigating international safety standards requires rigorous certification frameworks. Backed by our ILAC-MRA recognized CNAS laboratory, every OEM/ODM batch complies with CE, SIL, ATEX, and IECEx directives, providing global enterprises with frictionless customs clearance, legal compliance, and dependable local technical support.
With over 20 years of manufacturing mastery, 50+ patents, tens of millions of units deployed globally, and an in-house CNAS-accredited calibration laboratory, we provide end-to-end custom engineering, superior cost efficiency, and uncompromising quality assurance.
Our core product lines are fully certified under rigorous international standards, including CE, SIL, ATEX explosion-proof ratings, and ISO9001 quality management benchmarks, ensuring seamless regulatory compliance worldwide.
Every single unit undergoes automated multi-point calibration and environmental stress testing inside our CNAS-accredited laboratory, which operates strictly in accordance with ISO/IEC 17025 standards to guarantee absolute measurement traceability.
Thanks to our newly expanded smart manufacturing base in Deyang and streamlined SMT production lines, we maintain high inventory readiness and flexible scheduling, ensuring rapid turnaround times for both standard and customized global orders.
