Chengdu Factory & Office
Deyang Factory
We manufacture tens of millions of detector units annually, protecting plants in petrochemicals, mining, energy distribution, and logistics. Our system features integration with automatic solenoid shut-off valves for active gas control.
Xinhaosi maintains a CNAS-accredited testing laboratory. Every product undergoes strict validation to ensure accurate calibration and reliable performance under high humidity and temperature variations.
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 and SIL.
Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise" and "National Quality Leading Enterprise in the Gas Alarm Industry." We are a member of the China Fire Protection Association and the main drafting organization for national standards on solenoid valves, further confirming our industry influence and reputation.
Our CNAS-accredited laboratory operates in accordance with ISO/IEC 17025. It provides traceable testing services for gas detection systems, solenoid valves, and safety shut-off systems, ensuring international market access and regulatory compliance.
Our network monitoring software utilizes historical data analysis to help prevent system failures and minimize maintenance overhead.
We developed a certified maximum-point networked monitoring system that supports rapid communication over long distances.
Engineered with cast aluminum and stainless steel housings, protecting internal sensor modules from corrosive gases and moisture.

Maximizing value through vertical integration, component availability, and engineering capacity
Sourcing fixed-type gas detectors from a leading Chinese manufacturer offers significant advantages in lead times, pricing, and system scale. Key benefits of our production ecosystem include:
Large-scale projects require reliable supplier partners. Xinhaosi provides transparency at every step, offering clear inspection protocols, batch test results, and CNAS calibration certificates.
This approach helps system integrators qualify our equipment for demanding chemical, utility, and mining projects.
Ensuring compliance and seamless integration with existing industrial control networks
Industrial gas detection requires alignment with regional safety standards. We manufacture detectors to comply with major explosion-proof guidelines, including ATEX, IECEx, and China Ex standards, ensuring smooth site approvals.
Our transmitters support standard industrial outputs, including 3-wire 4-20mA analog loops, Modbus RTU (RS485), and addressable relays. This allows integration into DCS, PLC, and SCADA systems.
We work with global distributors to support local calibration, field training, and startup assistance. This helps ensure systems operate reliably from initial installation onward.
Reliable gas safety solutions for diverse industrial sectors
Continuous monitoring of flammable gases, crude vapors, and toxic hydrogen sulfide (H₂S) in refining and storage areas.
Monitoring methane (CH₄) buildup and oxygen depletion in wet wells, digestion tanks, and treatment facilities.
Protecting solvent recovery plants, paint booths, and assembly halls from volatile organic compound (VOC) vapor accumulation.
Reliable monitoring for early hydrogen (H₂) leaks and off-gas emissions in battery storage and charging areas.
The transition toward IoT connectivity, predictive diagnostics, and advanced sensor modules
Modern industrial operations require high-precision monitoring that integrates easily with plant control systems. Development in gas detection technology centers on three main areas:
Smart plug-and-play sensor elements simplify maintenance by allowing module exchange in hazardous locations without needing a complete device disassembly.
Wireless protocols (such as LoraWAN or WirelessHART) enable cost-effective installation in remote areas, reducing cabling costs while maintaining robust reporting.
By tracking baseline sensor performance over time, internal diagnostics can alert maintenance teams to clean or calibrate sensors before they fail.
The safety market is transitioning from simple warning systems to automated response systems. Our detectors link directly with quick-closing emergency shut-off valves.
If a gas leak is detected, the system triggers the shut-off valve to stop the gas flow before flammable levels are reached, providing proactive site safety.
