Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications, including national compulsory Products Certification, explosion-proof certification, fire product certification, CPA measurement instrument type approval certificate, and international approvals as CE, SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise", "National Quality Leading Enterprise in the Gas Alarm Industry," member of the China Fire Protection Association, and the main drafting organization for the national standard of solenoid valves, further confirming its industry influence and reputation.
In the field of intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. 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.
Analyzing why partnering with leading Chinese safety technology factories yields optimal product lifecycles, cost efficiencies, and engineering compliance.
Choosing an industrial-grade propane gas leak detector from Chengdu and Deyang, China, offers significant supply-chain advantages. Xinhaosi coordinates all primary manufacturing stages under one unified operating framework. From die-casting of heavy duty, explosion-proof, flame-retardant enclosures to the precise assembly of surface mount technology (SMT) PCBA boards, we minimize third-party vulnerabilities. Our direct control over core components like the solenoids in the KT-XF5 Series and the sensor housing in the XP4000 series ensures uniform quality, faster turnaround times, and highly stable performance during unexpected system loads.
In life safety equipment, calibration precision cannot be negotiated. China's top gas detector manufacturers leverage advanced automated calibration chambers. These chambers use precision-blended, traceable gas mixtures (e.g., standard propane, methane, or carbon monoxide) to calibrate and verify sensor responses. Our CNAS-accredited laboratory operates strictly under the ISO/IEC 17025 framework. This accreditation ensures that every gas detection controller, such as the JB-TB-AT2020SEL, undergoes rigorous temperature compensation, relative humidity cycling, and vibration endurance tests. These protocols guarantee that our detectors perform reliably, whether they are installed in extremely cold environments or near hot industrial machinery.
Sichuan Province, the core energy hub of Southwest China, provides access to top-tier engineering talent and specialized industrial clusters. By using these regional resources, we can rapidly develop and deploy complex technology. This includes multi-point bus-type networks, integrated IoT systems (GPRS, 4G, LoRaWAN), and smart safety shut-off systems. This research and development capability allows us to offer customized OEM and ODM solutions to global procurement offices, safety engineers, and international distributors at a highly competitive total cost of ownership (TCO).
We utilize high-selectivity catalytic bead sensors for rapid LEL response and NDIR infrared absorption sensors for long-term stability in oxygen-depleted or corrosive atmospheres.
Housings built with heavy-duty cast aluminum or 316 stainless steel, meeting international Ex d IIC T6 Gb explosion-proof ratings for hazardous industrial zones.
Normally open/closed auto-interlocking valves designed to cut off the main pipeline supply instantly when combustible gas thresholds are crossed.
Bridging the gap between raw hardware manufacturing and field safety integration. How we design specialized setups for industrial and commercial environments.
Enclosed parking facilities require constant monitoring for both toxic vehicle emissions and potential combustible gas leaks from LPG-powered vehicles. Our specialized carbon monoxide and propane monitoring system integrates the OEM AT2004BIV-CO Carbon Monoxide Detector with localized alarm panels. Utilizing a bus-type network architecture, the system coordinates multiple detection nodes. When gas concentrations rise, the controllers automatically trigger high-volume ventilation fans and shut down the main incoming gas lines using industrial solenoid valves. This mitigates risks without needing manual operator intervention.
Managing citywide gas pipeline networks requires continuous monitoring across widespread distribution points. For underground utility shafts, our GT-AT0616 Series Underground Shaft Combustible Gas Monitoring Device offers high reliability under harsh conditions. To support these networks, we deploy the GT-AT0636 Series Wireless Intelligent Terminal. These terminals use NB-IoT or LoRaWAN communication to transmit real-time gas level telemetry to central command offices. By using low-power, wide-area communication protocols, utilities can detect pressure drops or gas leaks early, helping to prevent catastrophic incidents before they occur.
Petrochemical processing plants operate in demanding conditions where high heat, dust, and corrosive vapors are common. In these environments, simple detectors can fail prematurely or generate false alarms. Our explosion-proof gas detectors, including the XP4000 series, feature intelligent self-diagnostic electronics. When paired with the FD2010 Triple Infrared Flame Detector, they form a complete, fast-acting hazard mitigation network. In this setup, the flame detector monitors for infrared radiation from fires, while the gas detectors track leaking hydrocarbons, triggering immediate shut-down sequences through the KT-XF5 solenoid valves.
