Advanced gas detection hardware optimized for urban environments, hazardous zones, and IoT smart grid integrations.
The San Francisco Bay Area operates under some of the most rigorous health, safety, and environmental standards in the United States. Driven by the California Fire Code Title 24, Part 9, and strict municipal building codes, residential developments, commercial high-rises, and industrial bioscience facilities are mandated to deploy sophisticated gas detection architecture. These systems protect occupants against volatile organic compounds (VOCs), methane, carbon monoxide, and other hazardous gases.
Additionally, Northern California's active seismic context requires gas safety technology that integrates directly with automatic gas shut-off valves (ASVs/OSOV). These valves isolate main lines immediately when a seismic trigger or a concentration threshold is crossed. For facility engineering directors in South San Francisco’s biotech corridor and Silicon Valley data centers, deploying dependable gas detector controllers is not merely an optional safety protocol—it is critical for compliance and business continuity.
Our capabilities meet the demand of large-scale infrastructure projects, OEM partnerships, and utility providers worldwide.
Empowering the international safety marketplace through innovative manufacturing, precision calibration, and responsive engineering.

Founded in 2003, Xinhaosi is one of the most influential and trusted brands in the global gas safety industry. Over the past two decades, we have steadily built a robust and comprehensive production and service system, which integrates cutting-edge R&D, intelligent manufacturing with advanced automation equipment, digital marketing across global channels, professional after-sales support with an experienced technician team, flexible OEM/ODM services, as well as CNAS-Accredited laboratory calibration services that meet international standards.
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.
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 such as CE and SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise" and "National Quality Leading Enterprise in the Gas Alarm Industry," confirming its global safety footprint.
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.
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. Operating in accordance with ISO/IEC 17025, our facilities provide traceable, high-fidelity calibration for complex sensor setups, ensuring that products imported by Bay Area developers or industrial procurers conform perfectly to native ANSI/UL benchmarks.
Helping international enterprises meet sustainability goals, regulatory demands, and building automation requirements.
Our controllers support Modbus RTU, BACnet/IP, and wireless options like LoraWAN and NB-IoT. This ensures simple integration with building management systems (BMS) in smart commercial buildings.
Direct output channels allow immediate integration with emergency shut-off valves. This ensures lines are closed within milliseconds of gas leak detection, preventing ignition.
Equipped with advanced electrochemical and catalytic combustion sensors, our systems maintain baseline stability and offer low cross-sensitivity to standard household solvents.
