Premium grade combustible gas alarms, controllers, and interlock units for high-risk zones.
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.

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," member of the China Fire Protection Association, and acts as the main drafting organization for the national standard of solenoid valves.
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.
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, it provides reliable and traceable testing services for gas detection, solenoid valves, and safety apparatus, ensuring frictionless access to global markets.
Transitioning from basic sensors to AI-enabled, self-calibrating edge systems for global emissions mitigation.
By shifting from standard catalytic bead sensors to MEMS-based semiconductor designs and Tunable Diode Laser Absorption Spectroscopy, we are lowering power draw by 70% while improving targeted gas selectivity. This mitigates cross-interference issues caused by household pollutants or ambient vapors.
Deploying advanced wireless modules supporting NB-IoT, LoRaWAN, and 5G network topologies. These systems allow continuous real-time transmission of hazardous concentration levels to cloud dashboards, facilitating rapid smart shut-off protocols without relying on hardwired local systems.
Embedding localized edge machine-learning models into our controller units. These algorithms parse baseline fluctuation trends, enabling smart predictive diagnostics and alerting control teams of a slowly developing micro-leak days before standard sensors would trigger a static alarm threshold.
Custom hazard mitigation frameworks for modern smart cities, energy fields, and factories.
Our heavy-duty, explosion-proof transmitter arrays (e.g., XP3000 & XP4000) are engineered to withstand corrosive vapors and extreme temperature ranges. Integrated with centralized controllers, they secure gas processing terminals and offshore drilling platforms.
We deploy high-integrity pressure monitoring hubs combined with autonomous solenoid valve interlocks to secure city gate stations and subterranean distribution networks. In case of a pipeline breach, the system triggers automated zoning shutoffs within seconds.
For large-scale housing complexes, we supply multi-point bus-type gas detectors. These interface with building automation systems to handle mechanical exhaust control and sounder signals, ensuring resident safety and compliance with international standards.
Leveraging automated manufacturing pipelines and vertically integrated supply structures to guarantee product quality.
Operating two dedicated production bases in Sichuan enables Xinhaosi to mitigate regional infrastructure risks. This ensures continuous logistics capability for global OEM/ODM orders even during periods of heavy demand. Our automated calibration tunnels use precise, traceable standard gases to calibrate every device, ensuring reliable performance in the field.
By producing tens of millions of units annually, we secure deep raw material buying power. This allows us to protect our global clients from key component shortages and volatile pricing, delivering high-performance safety equipment at highly competitive prices.
A reliable supply partner helping global enterprises navigate safety regulations and certification requirements.
Exporting gas leak safety devices requires navigating complex compliance pathways. Our design architectures adhere to ATEX/IECEx explosion-proof standards, SIL-2 (Safety Integrity Level) functional safety criteria, and European CE directives. We work with certifying bodies to ensure our commercial designs can be quickly adapted to fit regional regulations in the Middle East, South America, and Southeast Asia.
Engineering procurement houses require comprehensive documentation packages. We provide 3D CAD step files, detailed electrical loop schematics, sensor cross-sensitivity indexes, and clear calibration manuals. This ensures seamless integration into plant DCS systems, SCADA setups, and fire and gas panels via standard Modbus RTU or BACnet IP protocols.
