Founded in 2003, Xinhaosi has stood at the absolute forefront of electronic detection technology, serving as one of the most reliable and influential manufacturers in the global gas safety sector. By applying state-of-the-art sensory architectures and intelligent control protocols, we turn invisible atmospheric dangers into structured, actionable safety data.
Over two decades, we have focused on customer-centric design and strict adherence to international safety directives. Our mission is to secure industrial complexes, Municipal pipelines, commercial complexes, and modern smart homes. Powered by Industry 4.0 production standards, we configure robust, responsive, and precise telemetry gas systems to construct a safer, zero-accident environment globally.
We utilize diverse sensor technologies to address unique physical conditions, operational life cycles, and cross-sensitivity requirements across challenging industrial atmospheres.
Engineered for combustible gases like Methane (CH4) and Propane (C3H8). These sensors detect gas concentrations by measuring resistance changes caused by catalytic combustion on active platinum coils. They offer high stability, long-term accuracy, and resist false alarms from atmospheric variations.
Optimized for toxic concentrations (CO, H2S, O2, NH3). It monitors chemical oxidation-reduction reactions on a sensing electrode, generating a current output directly proportional to the gas volume. This technology ensures sub-ppm resolution and low power consumption for smart IoT devices.
A non-contact technology utilizing gas absorption wavelengths to target volatile organics, hydrocarbons, and Carbon Dioxide. Free from poisoning by silicones or sulfur compounds, NDIR delivers an extended operational lifespan (10+ years) and works effectively in oxygen-deficient areas.
The industry is transitioning toward digitalized safety networks. Xinhaosi integrates LoRaWAN, NB-IoT, 4G/5G Cat-M protocols, and standard MODBUS RTU interfaces directly into its device lines. By combining IoT connectivity with on-board AI algorithms, our sensors perform dynamic temperature compensation, self-calibration, and baseline correction, minimizing false alarms while offering real-time cloud diagnostic telemetry.
We manufacture specialized detection, monitoring, and automated response systems tailored to four key safety applications.
High-precision, explosion-proof detection systems designed to endure harsh refinery, chemical processing, and mining environments. Features ATEX, IECEx, and SIL2 compliance.
Smart detectors tailored for kitchens, boiler rooms, and light commercial buildings. Offers localized alarms, status displays, and relay interfaces for safety shut-off valves.

Find key answers about sensor technologies, installation guidelines, calibration cycles, and safety standards.
Catalytic bead sensors generally have an operational life of 3 to 5 years under normal conditions. They are subject to gradual degradation from exposure to silicones, halogenated compounds, or lead, which can reduce sensitivity. In contrast, Non-Dispersive Infrared (NDIR) sensors are optical and do not interact directly with the gas. This makes them resistant to sensor poisoning and extends their operational lifespan to 10 years or more.
For safety-critical industrial environments, calibration is recommended every 6 months, along with regular functional bump tests. In stable applications, annual calibration may be sufficient. Calibration should adjust both the zero baseline and span values using certified calibration gases to ensure accuracy over time.
Emergency shut-off systems typically use normally open (N.O.) solenoid valves. During normal operation, the valve remains open without drawing power, preventing coil overheating. In a gas leak, the gas detector sends a brief electrical pulse (typically 12VDC) to trigger the solenoid. This instantly drops the internal plug and stops the gas flow. The valve must be manually reset once the area is safe. Normally closed (N.C.) valves are used in systems that require the valve to shut automatically if electrical power is lost.
Electrochemical and catalytic sensors can sometimes react to non-target gases, such as showing cross-sensitivity to Hydrogen (H2) during Carbon Monoxide (CO) monitoring. To minimize this, Xinhaosi uses specialized filters and dual-sensor arrays. By combining readings from multiple sensors and applying compensation algorithms, our systems filter out background gases to reduce false alarms.
SIL 2 (Safety Integrity Level) certification, based on the IEC 61508 standard, measures the reliability of a safety function. A SIL 2 certification indicates that the gas detector has a low probability of failure on demand, making it suitable for hazardous process industries like chemical plants and oil refineries, where system failure could lead to severe consequences.
Installation height depends on the target gas density relative to air. For lighter gases like Methane (natural gas), detectors should be placed 30cm to 100cm below the ceiling, close to the source. For heavier gases like Propane or LPG, detectors should be positioned 30cm above the floor to capture gas that accumulates at lower levels. Detectors should be located within 1.5 to 4 meters of appliances, away from direct drafts, ventilation ducts, and high humidity.
