Explore our state-of-the-art detectors and safety accessories engineered to withstand harsh environments and satisfy rigorous international standards.
In an era defined by aggressive decarbonization targets, accelerating global industrialization, and stringently enforced workplace safety standards, gas leak detection has shifted from a reactive facility requirement to a proactive, data-driven security asset. As a premier OEM Natural Gas Leak Detector Supplier & Manufacturer, Xinhaosi operates at the intersection of sensor innovation and life protection systems.
Natural gas, primarily composed of methane ($CH_4$), is crucial for power generation and chemical synthesis, yet its highly combustible nature demands immediate, error-free monitoring. Traditional single-point detection architectures are no longer sufficient to secure complex oil refineries, chemical production complexes, and extensive urban municipal pipelines. Modern industrial operators require fully integrated, multi-layered networks featuring gas leak detectors, high-speed automated shut-off solenoid valves, and centralized control systems connected to cloud platforms. Xinhaosi delivers this comprehensive matrix by matching high-quality manufacturing capability with specialized engineering expertise.
Deploying advanced catalytic combustion and non-dispersive infrared (NDIR) sensors to eliminate false alarms and guarantee immediate reaction times in hazardous areas.
Designing and manufacturing pioneering bus-type networked gas monitoring units that consolidate thousands of physical detection nodes into a single, intuitive interface.
Utilizing proprietary software algorithms to track historical drift, evaluate sensor health, and trigger maintenance alerts before critical failures occur.
Established in 2003, Xinhaosi has built a world-class manufacturing presence. Through our integrated facilities in the Chengdu Factory & Office and the modern, expanded Deyang Factory, we provide vertical manufacturing that handles everything from raw PCB assembly to finished, certified gas detectors.
Operating in strict compliance with the ISO9001 Quality Management System, our production floors utilize automated SMT (Surface Mount Technology) assembly lines, automated calibration cells, and robotic testing units to maintain high manufacturing repeatability. Every single combustible gas detector and gas control unit undergoes multi-stage parameter calibration against known target gas concentrations to ensure real-world accuracy.
By controlling our tooling, molding, component verification, and final compliance testing, we provide exceptional OEM/ODM flexibility. We easily adapt mechanical structures, communication protocols (Modbus, BACnet, 4-20mA, LoRaWAN), and enclosure ratings (IP66, IP67) to match our clients' unique regional requests and industrial layouts.
Chengdu Research, Development & Manufacturing Headquarters
To address the rising global demand for reliable gas safety equipment, Xinhaosi built and opened our state-of-the-art Deyang Factory. This facility boosts our annual production capacity into tens of millions of units, making us one of the largest specialized manufacturers in the gas safety sector.
This expansion allows us to streamline bulk manufacturing processes, reduce customer lead times, and optimize supply-chain costs. It supports our efforts to make reliable gas safety technologies accessible globally, ensuring that whether a client requires localized residential alarms or heavy-duty industrial systems, our production capability can deliver.
Automated Deyang Valve and Gas Safety Equipment Plant
CNAS-Accredited ISO/IEC 17025 Calibration and Testing Facility
Xinhaosi is dedicated to rigorous technical validation. Our central testing facility holds accreditation from the China National Accreditation Service for Conformity Assessment (CNAS). It operates in compliance with ISO/IEC 17025, the international standard for testing and calibration laboratories, ensuring mutual recognition under the ILAC-MRA framework.
Our core product lines hold key international and regional approvals, including the national compulsory Product Certification (CCC), explosion-proof certifications, fire product certifications, CE, and SIL (Safety Integrity Level) ratings. This compliance profile ensures seamless integration into projects with demanding risk management profiles.
Through continuous R&D investment, Xinhaosi has secured over 50 patents and software copyrights. A key innovation is our proprietary graphical monitoring software system, designed for real-time gas detection and alarm tracking. This platform uses historical data logging to support predictive maintenance protocols, helping clients reduce equipment downtime by up to 30%.
Furthermore, Xinhaosi pioneered China's first networked bus-type gas leakage monitoring system, as well as a specialized, multi-point monitoring system approved by national public safety bodies. We are also recognized as a key drafting organization for the national technical standards governing gas safety solenoid valves, demonstrating our leadership in the safety sector.
From heavy chemical refining facilities to residential buildings, Xinhaosi systems are engineered to perform in diverse environments.
Upstream, midstream, and downstream operations require rugged safety systems. In these settings, environments are corrosive and hazardous gases are common. Our explosion-proof detectors (certified for Zone 1 and Zone 2) use flameproof enclosures and intrinsically safe electronics to deliver reliable monitoring in harsh, variable weather conditions.
Urban gas pipelines and city gate stations require continuous, widespread monitoring. Xinhaosi’s bus-type controllers integrate gas detectors and automated emergency valves. If a leak is detected, the controller triggers local alarms and activates safety valves to shut off gas flow, helping prevent accidents.
In multi-family residential complexes, hotels, and industrial kitchens, gas safety requires simple, reliable, and cost-effective solutions. Our residential detectors feature loud audio alarms, visual indicator lights, and built-in relays to control residential shut-off valves, bringing professional safety technology to everyday environments.

Technical answers regarding detector calibration, sensor lifetimes, and OEM customization capabilities.
We utilize catalytic combustion, electrochemical, and non-dispersive infrared (NDIR) sensors, depending on the target application. Catalytic combustion is highly effective for cost-efficient detection of LEL (Lower Explosive Limit) levels in residential and commercial spaces. NDIR sensors offer superior longevity, function reliably in oxygen-depleted atmospheres, and resist chemical poisoning, making them ideal for heavy petrochemical and industrial settings.
We recommend calibrating industrial detectors every 6 to 12 months, in accordance with local safety regulations and operating environment conditions. Because our testing laboratory is CNAS-accredited and meets ISO/IEC 17025 standards, all calibration services and test reports are fully traceable, satisfying international compliance and auditing demands.
Our customization services cover enclosure design, custom branding, modifications to PCB layouts, communication protocol integration (including Modbus, 4-20mA, LoRaWAN, and Zigbee), and adjustment of alarm relay configurations. We can customize solutions to meet specific explosion-proof classifications and IP protection ratings, matching the requirements of your target market.
Xinhaosi safety systems hold CE and SIL (Safety Integrity Level) ratings, alongside domestic CCC, fire safety, and explosion-proof certifications. Our manufacturing sites operate under ISO9001 quality management standards, ensuring consistent, compliant production for global export.
