Explore our flagship range of explosion-proof detection systems, advanced control cabinets, and emergency shut-off valves certified for critical applications.
Industrial hydrocarbon detection has moved rapidly beyond simple detection of visible leakage. In today’s complex manufacturing, petrochemical, and municipal environments, detecting trace amounts of volatile organic compounds (VOCs) and combustible hydrocarbons (such as methane, propane, butane, and heavier alkanes) is critical to preventing catastrophic failures. Traditional catalytic bead sensors, while robust, are susceptible to sensor poisoning from silicones, sulfides, and halogenated compounds. This vulnerability has fueled the industry-wide transition toward Non-Dispersive Infrared (NDIR) detection and Photoionization Detectors (PID).
Modern hydrocarbon detectors utilize NDIR sensors to target the specific infrared absorption wavelengths of carbon-hydrogen (C-H) bonds. Because this optical measurement does not require direct chemical reaction, NDIR sensors boast exceptional longevity, immune to poisoning and capable of operating in oxygen-deficient environments (e.g., nitrogen-purged tanks or deep underground shafts). For ultra-low concentration monitoring (ppb levels) of aromatics and complex VOCs, Photoionization Detection (PID) acts as the premium defense line, utilizing ultraviolet light to ionize molecules and accurately assess toxicity risks in petrochemical refineries.
Making unknown gas leak risks clear, visible, and controllable.
Founded in 2003, Xinhaosi has established itself as one of the most influential and reliable brands in the global gas safety industry. Our legacy is built on the deployment of advanced electronic detection technologies designed to safeguard the safe operation of industrial plants, secure the energy supply grids of major metropolitan areas, and guarantee peace of mind in millions of households globally.
Through decades of R&D, we have integrated complete safety chains: from precision sensing units and flame detection devices to control panels and shut-off valves. This full-spectrum approach allows us to deliver intuitive, durable, and highly precise instrumentation capable of meeting the stringent requirements of modern industrial environments.
EHS compliance managers must balance local regulations with international requirements. Global procurements prioritize equipment carrying verified ATEX, IECEx, and SIL2 certificates, facilitating streamlined approval cycles for plant installations.
Procurement isn't just about purchase price; it is about minimizing the total cost of ownership. Smart optical and NDIR hydrocarbon detectors reduce calibration intervals, lower field-maintenance overheads, and drastically cut downstream replacement costs.
Integration with Modbus, HART, and Ethernet protocols enables smart assets to report real-time status directly to centralized SCADA systems. Advanced diagnostic logging prevents false alarms and enables predictive scheduling for sensor calibration.
Empowered by modern technology and full-chain system integration, we provide comprehensive protection for commercial, municipal, and industrial operations.

Manufacturing industrial-grade safety equipment requires precision. At Xinhaosi, we combine scale with rigorous quality control to deliver reliable gas monitoring systems globally. Our production lines feature automated optical inspection (AOI), high-precision environmental chamber tests, and automated calibration setups to ensure each sensor performs to standard.
Through strategic supply chain management, we maintain steady access to essential raw components and critical sensing element wafers. This resilience minimizes manufacturing lead times and shields our global distributors from market supply shocks. By maintaining high vertical integration—from raw metal forging for explosion-proof chambers to proprietary chip design—we guarantee stable delivery schedules even during macro supply challenges.
Different environments face distinct challenges. We configure our sensing solutions to meet the specific requirements of various operating conditions.
Underground shafts are prone to pocketing heavier-than-air combustible gases like propane and butane. The GT-AT0616 and AT0605 series are designed specifically to operate in high-humidity, low-oxygen underground environments, providing early warnings to protect municipal work crews.
Refineries process a wide variety of flammable hydrocarbon compounds daily. Our explosion-proof detectors (GTYQ-AT0602 / GTYQ-AT0501) monitor large processing areas, sending real-time reports to main JB-TB-AT2020DX controllers to trigger emergency shutdown protocols.
For commercial spaces and LNG distribution terminals, rapid response is essential to safety. By combining household/commercial gas safety units (JT-AT2009 / JT-AT2013A) with XF3III solenoid valves, we help facilities isolate gas leaks at the source the moment they are detected.
