Explore our flagship lineup of industrial explosion-proof monitors, household safety sensors, smart controllers, and interlock control systems, designed and engineered at our specialized manufacturing facility.
Founded in 2003, Xinhaosi is one of the most influential and reliable brands in the gas safety industry. Over two decades, we have evolved into a premier OEM methane detector manufacturer and factory, driving systemic safety innovations across petrochemical complexes, municipal pipelines, and residential zones. We utilize advanced electronic detection technology to make unknown gas leak risks clear and visible, optimizing safety architectures globally.
Powered by cutting‑edge production systems and technology, we deliver more advanced, intuitive, and precise gas safety solutions for shaping a safer future world. Our manufacturing capabilities bridge high-mix low-volume specialized components with mass-scale commercial configurations, providing unmatched stability and longevity.
Industrial buyers, engineering firms (EPCs), and safety administrators require flexible OEM integration strategies. Today's global procurement trends focus on digital telemetry, explosion-proof construction, and long-term sensor calibration stability. As a dedicated OEM partner, we customize methane sensing products to fit specialized market demands, offering private labeling, localized certifications, and customized circuit topologies.
Mandatory strict compliance protocols including ATEX, IECEx, UL, and SIL2/3 functional safety guidelines to secure operations in hazardous environments.
Seamless communications including LoRaWAN, NB-IoT, RS485 Modbus, and 4G to support intelligent, real-time safety monitoring dashboards.
Advanced catalytic combustion, electrochemical, and infrared sensing (NDIR/TDLAS) to achieve long-term stability and minimize sensor drift.
Our proprietary manufacturing technologies span all levels of industrial, commercial, and residential operations. Empowered by technology, with full-chain integration and comprehensive protection, we shape the future with intelligence.
Detection Systems - Safety First from Precision Sensing
Gas Detectors - Home Safety from Gas Monitoring
Gas Solenoid Valves - Protecting from the Source
Distribution & Monitoring - Smart Sensing for Urban Gas
Our factory incorporates automated surface mount lines (SMT) and gas-flow calibration rooms. We use trace-methane balance chambers to calibrate each device to standard concentrations (e.g., 50% LEL, 10% LEL), ensuring minimal drift over years of operation.
Unlike single-point sensor assemblers, we offer integrated safety solutions. Our controllers connect directly to our gas solenoid valves (e.g., the XF3 and BT-XF5 series), immediately shutting down upstream gas lines when critical alarm thresholds are reached.
Our R&D focuses on enhancing sensitivity, reducing cross-sensitivity to non-target hydrocarbons, and extending sensor lifespans. By upgrading from basic catalytic bead sensors to advanced optical sensors, we protect infrastructure from false alarms and unmonitored hazards.
| Sensing Technology | Typical Lifespan | Power Profile | Key Advantages | Ideal Application |
|---|---|---|---|---|
| Catalytic Combustion | 3–5 Years | High (Continuous heating) | Highly cost-effective, durable | Household gas detectors (JT-AT2008) |
| Electrochemical | 2–3 Years | Very Low | Specific targeting, low-power | Explosion-proof portable detectors |
| Non-Dispersive Infrared (NDIR) | 5–10 Years | Medium | No poison risk, works in oxygen-free areas | Industrial pipeline duct detection |
| TDLAS (Laser Absorption) | 10+ Years | Medium-Low | Zero drift, extreme selectivity (ppm levels) | Underground shafts & remote monitoring |
Safety systems require verified field performance. Our factory operates under ISO9001:2015 quality frameworks, deploying multi-stage automated optical inspection (AOI) alongside automated calibration chambers. We verify that each gas detector and controller complies with target regulatory requirements:
Our industrial gas monitors (such as the GTYQ-AT0503 and AT0602 models) are built with heavy cast-aluminum or stainless-steel explosion-proof housings, certified for hazardous Zone 1 and Zone 2 operations.
Our gas detector controllers, such as the JB-TB-AT2020LH, are designed for functional safety, featuring built-in microcontrollers that monitor fault parameters to ensure high reliability.
Our household combustible detectors (such as the JT-AT2009 and JT-AT3068 series) are calibrated to meet European residential standard EN 50194, triggering alarms well below hazardous LEL levels.

Catalytic combustion sensors burn trace amounts of gas on an active bead to measure resistance change. They are cost-effective but can suffer from sensor poisoning (e.g., from silicones or sulfur compounds) and require oxygen. NDIR (Non-Dispersive Infrared) sensors measure gas using infrared light absorption, which prevents sensor poisoning, works in oxygen-free environments, and provides a longer operational life (often over 10 years).
When a detector (like the JT-AT2004BII) senses methane levels exceeding its programmed threshold, it transmits a signal via the bus protocol to our interlock control box (such as the JB-MK-AT2042X). The control box processes this input and triggers a linked output, immediately closing the gas solenoid valve (such as the XF3 series) to stop gas flow at the source.
Yes. As an OEM manufacturer, we design and produce detectors tailored to the technical requirements of different regional markets. This includes modifying enclosures to meet explosion-proof ratings (e.g., ATEX Zone 1/2), adjusting alarm levels to meet local safety standards, and incorporating specific communication protocols (such as Modbus, 4-20mA, or IoT networks).
Standard product orders are fulfilled quickly using our existing factory inventory. Custom OEM/ODM designs—which can include custom enclosure colors, private branding, unique firmware thresholds, or specialized output relays—typically have a lead time of 4 to 8 weeks, depending on the design scope and certification updates required.
Our safety products and systems are integrated across leading utility companies, petrochemical plants, and residential networks worldwide.
