Explore our core engineering portfolio of industrial combustible detectors, control interfaces, and automatic shut-off systems.
Founded in 2003, Xinhaosi has established itself as one of the most influential and trusted brands in the global gas safety and industrial monitoring industries. Over the past two decades, we have engineered a highly integrated production and service ecosystem that incorporates cutting-edge R&D, advanced automated manufacturing, comprehensive digital verification channels, and reliable OEM/ODM systems.
Our CNAS-Accredited laboratory provides calibration services compliant with international standards, helping pipeline operators, plant managers, and procurement leads fulfill critical compliance criteria. Driven by the mission of "Making Gas Safety Accessible Everywhere," we design systems that adapt to extreme environments—protecting lives and infrastructure in petrochemical plants, urban distribution networks, and industrial manufacturing sites.
Adhering to strict ISO9001 quality management system standards, Xinhaosi's core products hold a full spectrum of authoritative certifications. These include China Compulsory Certification (CCC), Explosion-Proof Protection Certification (Ex d IIC T6 Gb), Fire Product Approval, and CPA Measurement Instrument Type Approval. Internationally, our products align with CE directives and Safety Integrity Level (SIL2) certifications.
Our in-house calibration lab is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized globally under the ILAC-MRA framework. Operating in compliance with ISO/IEC 17025, our facility runs rigorous stress testing on detection sensors, confirming stability, response time (T90), cross-sensitivity profiles, and temperature/humidity compensation curves.
Xinhaosi's innovations include a graphical monitoring platform that enables predictive maintenance, reducing equipment failure rates by over 30%. By pioneering China's first networked bus-type gas leakage monitoring system, we have defined a benchmark for commercial gas safety control panels and multi-channel telemetry systems.
Advancing from classic detection principles to high-fidelity, zero-drift optical gas sensing methodologies.
Leverages a specific absorption line of CH4 at 1653nm. TDLAS provides absolute selectivity to methane, avoiding false alarms caused by solvents, alcohols, or other heavy hydrocarbons. Offers zero sensor drift and a functional lifespan exceeding 10 years.
Utilizes dual-wavelength infrared light paths to compute gas concentration. It is highly resistant to poisoning (from silicones or hydrogen sulfide) and performs reliably in oxygen-depleted atmospheres. Ideal for localized high-concentration monitoring.
A cost-effective solution for detecting concentrations from 0 to 100% LEL. Xinhaosi uses premium catalytic elements with custom-engineered filtration layers to extend operational lifetime and minimize baseline drift in diverse environmental settings.
Our product development cycle is focused on embedding low-power wide-area network (LPWAN) protocols, such as LoRaWAN and NB-IoT, directly into hazardous-area transmitters. By coupling these hardware designs with edge computing algorithms, future Xinhaosi methane detectors will dynamically calculate localized gas leak rates and diffusion directions, allowing plant personnel to mitigate safety hazards before concentrations reach the lower explosive limit.
Tailoring reliable explosion-proof and gas-monitoring systems to meet the demands of global industrial projects.
Wellheads, compressor stations, and processing facilities require continuous monitoring to identify fugitive emissions. Our flameproof methane transmitters (rated Ex d IIC T6) withstand extreme marine salt spray and desert heat, integration with RTU/SCADA systems via 4-20mA, Modbus RTU, or HART interfaces. This supports quick response and mitigation during unplanned gas leaks.
Our specialized underground monitoring devices (such as the GT-AT0616 and GT-AT0617 series) are designed for confined spaces, vaults, and utility corridors. Featuring IP67 ingress protection and low-power operations, these monitoring nodes continuously log methane build-up, protecting critical urban infrastructure and preventing localized hazards.
Refineries and chemical plants handle various combustible gases under high temperatures and pressures. Xinhaosi delivers an integrated defense system: fixed combustible gas detectors connected to centralized controllers (like the JB-TB-AT2020S), paired with high-flow emergency shut-off valves. This setup allows the system to automatically isolate gas lines in milliseconds if gas levels cross pre-set safety thresholds, preventing catastrophic incidents.
Xinhaosi's manufacturing ecosystem is split across two facilities in Chengdu and Deyang. Our production system leverages industrial automation and data integration to maintain steady output and delivery times, even under tight schedules.
By implementing advanced enterprise resource planning (ERP) and manufacturing execution systems (MES), we monitor the entire lifecycle of each methane detector—from surface-mount component placement on high-precision PCBs to final calibration inside testing gas chambers. Our supply chain relies on local components and verified raw material suppliers, buffering production against international logistics shifts.
OEM and ODM clients benefit from:
How we tailor gas detection equipment to align with international regulatory, electronic, and branding standards.
We configure gas transmitter communication outputs to match existing plant systems. Whether you use standard 4-20mA analog loops, Modbus RTU over RS485, HART protocols, or wireless networks like NB-IoT, our engineering team modifies firmware and interface boards to ensure straightforward integration.
Operating environments call for specialized materials. We supply heavy-duty cast aluminum or 316 stainless steel housings to protect internal electronics against seawater corrosion, dust ingress, and high pressures. This ensures durability in offshore platforms and chemical storage facilities.
For OEM system integrators, we offer private-label branding, customized enclosure colors, and custom packaging. We also share API protocols and control panel SDKs, helping clients integrate our methane detection hardware with their proprietary software platforms.
Building localized technical support networks to streamline import, commissioning, and calibration audits across major markets.
Compliance is a critical factor for global engineering firms. Xinhaosi design architectures conform with international standards. We supply full documentation packages for hazardous installations—including ATEX, IECEx, and CE declarations of conformity—speeding up local inspection and licensing processes.
To support global field operations, we offer technical assistance for commissioning, system architecture design, and localized device calibration. Our network of authorized distributors and service centers provides fast access to spare parts, routine calibration kits, and technical training, minimizing downtime for critical monitoring loops.

Answers to technical, regulatory, and mechanical questions for procurement officers and plant engineers.
TDLAS (Tunable Diode Laser Absorption Spectroscopy) targets a specific absorption wavelength of methane (typically 1653nm). This makes it highly selective, avoiding false alarms from other gases or chemical vapors. TDLAS sensors operate without drift and do not degrade when exposed to silicones, sulfur, or heavy hydrocarbons. In contrast, catalytic combustion sensors cost less upfront but require exposure to oxygen, need regular calibration, and can experience sensor drift or poisoning in demanding environments.
Our industrial gas detectors hold explosion-proof certifications (Ex d IIC T6 Gb) to verify safe operation in Zone 1 and Zone 2 hazardous areas. They comply with CE and SIL2 standards, indicating they meet safety performance requirements. For the Chinese domestic market, our instruments carry China Compulsory Certification (CCC) and CPA Metrological Approval.
Every methane detector undergoes automated testing at our ISO/IEC 17025 accredited CNAS laboratory. We calibrate devices using traceable standard gas mixtures, generating detailed verification reports. For OEM clients, we can preset calibration parameters to match specific targets (such as LEL levels or ppm ranges) based on local regional standards, simplifying on-site commissioning.
Standard lead times range from 3 to 6 weeks, depending on the level of customization (such as custom enclosures, proprietary communication boards, or custom software). Because our Chengdu and Deyang facilities utilize automated SMT lines and dedicated assembly stations, we can quickly scale up production to keep schedules on track.
Our industrial gas safety control panels (like the JB-TB-AT2020S series) monitor real-time outputs from methane detectors. If gas levels reach a pre-set threshold, the controller sends a high-current electrical pulse to the solenoid valve (such as the XF3 Series). This instantly closes the valve, cutting off the gas supply at the source to mitigate safety hazards.
