Engineered for extreme environments, accredited by CNAS, SIL, and global fire safety authorities.
In modern process industries and civil infrastructure, gas detection sensors act as the frontline of defense against industrial catastrophes. Buying directly from integrated Chinese factories provides global enterprises with a distinct structural advantage. These advantages go beyond simple cost reductions, extending deep into the supply chain ecosystem. At our facilities in Chengdu and Deyang, we specialize in high-reliability sensors capable of withstanding extreme temperatures, high pressure, and corrosive environments.
By localizing the entire production flow—from raw ceramic element conditioning to robotic sensor alignment—we guarantee stability. The concentration of component manufacturing hubs in western China allows us to source raw materials and deploy precision electronics rapidly. Consequently, we reduce production cycles for customized OEM orders to less than half the industry standard, ensuring high flexibility for custom projects.

These patents cover core technological areas, including a graphical monitoring system for gas detection and alarm, which enables predictive maintenance based on historical data to reduce equipment failure rates by over 30%, and a solenoid valve with flow monitoring functionality that integrates flow detection and alarm capabilities. The company also pioneered China's first networked bus-type gas leakage monitoring system and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security, demonstrating its leading position in cutting-edge technological research.
Our in-house laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. It operates in accordance with ISO/IEC 17025, the international standard for testing and calibration laboratories. It provides reliable and traceable testing services for gas detection and alarm products, solenoid valves, and related safety equipment. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities, certification bodies, and customers in China and overseas, helping to ensure product quality, safety compliance, and market access.

How Xinhaosi addresses real-world, high-risk detection challenges globally.
Refineries present one of the most demanding environments for gas sensors. The presence of sulfur compounds, high moisture, and constant vibration requires robust physical and electrical shielding. Our explosion-proof combustible gas detectors (e.g. GTYQ-AT0505/d) utilize high-grade pellistors and infrared sensors that withstand catalyst poisoning, reducing calibration frequency from months to years.
Deploying SIL-certified equipment ensures safety system integrity, preventing false positives that shut down entire production trains unnecessarily.
With massive gas transport piping networks carrying methane through residential areas, quick detection of pipeline breaches is critical. Xinhaosi’s networked bus-type leakage monitoring system acts as an early warning node, transmitting gas pressure anomalies and low-concentration leak events directly to central municipal management platforms.
Modern commercial buildings demand reliable Carbon Monoxide (CO) and Nitrogen Oxide (NOx) detection to ensure occupant safety while managing energy costs. The OEM AT2004BIV-CO monitors ventilation demand in real time. It activates ventilation shafts only when concentrations exceed threshold limits, generating substantial HVAC energy savings.
True safety requires more than detection; it requires immediate action. Xinhaosi's industry-first AI safety valve products interface directly with gas detectors. In the event of a high-alarm leak state, the system automatically triggers a solenoid valve to isolate the gas supply line, preventing explosive build-up.
The shift toward interconnected, predictive, and low-maintenance sensor networks.
By leveraging neural networks on cloud telemetry databases, safety officers can predict sensor failure before it happens, optimizing field maintenance scheduling.
New remote gas monitoring nodes operate via low-power mesh networks (LoRa, NB-IoT) using solar harvesting, bypassing costly trenching and cabling processes.
Next-generation optical systems allow the monitoring of multiple volatile organic compounds (VOCs) and combustible gases simultaneously on a single microchip.

Technical and logistical insights for gas detection system deployment.
Catalytic combustion sensors (pellistors) are cost-effective and detect a wide variety of flammable gases, but they can be poisoned by silicone, sulfur compounds, and halogenated hydrocarbons, and require oxygen to function. Non-dispersive infrared (NDIR) sensors are highly resistant to poisoning, do not require oxygen, and offer superior lifespan and stability, though they are limited to hydrocarbons and require higher initial capital investment.
Our transmitters and controllers support standard industrial protocols. These include linear 3-wire 4-20mA current loops and digital RS485 Modbus RTU, enabling easy integration with standard PLCs and DCS systems. We also offer addressable bus systems that reduce field wiring complexity.
CNAS is a signatory to the ILAC Multilateral Recognition Arrangement (ILAC MRA). This means calibration reports issued by our testing facilities are recognized in over 100 countries globally. This compliance helps streamline local regulatory approvals for our customers.
Electrochemical sensors for toxic gases typically last 2 to 3 years. Catalytic combustion sensors last between 3 to 5 years, depending on background gas exposure. Infrared sensors have the longest operational life, frequently exceeding 5 to 8 years under standard conditions.
Yes, our explosion-proof detectors feature Ex d IIC T6 Gb class ratings. This makes them suitable for Zone 1 and Zone 2 areas where explosive gas atmospheres are likely to occur during normal operation.
