Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications. These include national compulsory Products Certification (3C), explosion-proof certification, fire product certification, CPA measurement instrument type approval certificate, and international approvals such as CE and SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise", "National Quality Leading Enterprise in the Gas Alarm Industry," membership in the China Fire Protection Association, and serves as 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.
How Xinhaosi leverages breakthrough sensing technology and IoT analytics to lead the evolution of methane detection systems.
We are advancing beyond catalytic combustion to Tunable Diode Laser Absorption Spectroscopy (TDLAS). This tech eliminates false positives from VOC interference and provides gas specificity, ensuring targeted measurements down to ppm levels with virtually zero drift over years of field operation.
Incorporating intelligent localized computing algorithms inside gas transmitters allows real-time analysis of sensor deterioration. By tracking ambient humidity, temperature shock, and sensor age, our monitors predict failures up to 30 days before they occur, shifting safety paradigms from reactive to proactive.
Transitioning wired legacy systems to low-power WAN protocols (LoRaWAN, NB-IoT). Future monitors feature self-healing mesh networking topologies designed for wide-area chemical plants and urban pipe channels, ensuring continuous transmission under severe electromagnetic barriers.
Providing custom-tailored safety monitoring frameworks for various sectors demanding fail-safe methane gas mitigation.
Class I Division 1 and Zone 1 explosion-proof transmitters operating 24/7 in harsh refinery units. Seamless Modbus and 4-20mA integration to distributed control systems (DCS) with localized emergency shut-off gas valves.
Smart monitoring systems tailored for complex urban layouts, covering distribution manifolds and municipal utility tunnels. Featuring IP67-rated waterproof wireless monitors linked to the central command via secure cloud dashboards.
Sleek, highly reliable household methane alarms featuring intelligent self-check features, electrochemical or semiconductor sensors, direct gas valve linkages, and optional IoT smart-home application integration.
Xinhaosi's newly commissioned Deyang Plant represents the pinnacle of industrial gas instrumentation automation. By leveraging modern production techniques, we ensure our global partners receive consistent quality with high-volume scaling capabilities.
