Chengdu Factory & Office
Deyang Factory
Leveraging state-of-the-art production environments, our dual-base production facility strategy located in Chengdu and Deyang spans massive square footage designed for automated production lines, calibration hubs, and precise electronic assembly.
By implementing advanced robotics, automated surface mount technology (SMT), and integrated sensor test chambers, we guarantee consistent accuracy for every toxic gas sensor and controller unit dispatched globally. Our smart factory structures are equipped to handle high-volume procurement orders while maintaining customization flexibilities required by global OEM/ODM clients.
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 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," 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.
A Deep-Dive into Regulatory Alignment, Advanced Sensor Paradigms, and the Strategic Sourcing Advantages of China’s Semiconductor & Gas Safety Supply Ecosystem.
By establishing comprehensive manufacturing operations in Chengdu and Deyang, we leverage China's mature electronics and sensor component ecosystem. Our supply network guarantees a seamless flow of raw materials, silicon MEMS substrates, and advanced electrochemical cells, allowing us to maintain competitive lead times even during global component shortages.
Global integration requires localized safety assurance. We provide extensive localized field application engineering (FAE) support to ensure our products align with local safety regulations such as NEC, ATEX, IECEx, and EN European Standards. Our digital and analog telemetry interfaces integrate with distributed control systems (DCS) worldwide.
Large-scale industrial procurers demand transparency and quality tracing. With our CNAS-accredited calibration laboratories operating in compliance with ISO/IEC 17025, every sensor is individually calibrated and traceable. This strict verification standard ensures high reliability, minimizing false alarms and sensor drift.
Understanding the exact technological profile of gas detectors is vital for safety compliance officers and industrial engineers. Our factory produces gas sensors utilizing three distinct physical principles to optimize performance across applications:
From deep mining operations to modern smart cities, our safety networks are engineered for diverse and challenging environments.
Refineries require robust, explosion-proof, and corrosion-resistant sensor housings. Our SIL-certified, flameproof gas detectors monitor pipeline perimeters for methane, hydrocarbons, and toxic hydrogen sulfide gas leaks, with interlock control boxes triggering automatic shutoffs.
Underground operations face accumulation risks of combustible methane and toxic carbon monoxide. Our specialized series, including the AT0605 and GT-AT0616 Underground Shaft Monitors, provide early warnings in high-humidity, high-dust conditions.
Municipal gas networks rely on continuous telemetry. Our IoT-enabled smart pressure monitors and low-power residential detectors integrate with municipal utility grids to deliver real-time cloud data, ensuring rapid response to leak events.
Tracing our evolution from a specialized regional startup to an internationally recognized standard-setter in gas safety.
Highly targeted answers addressing real-world concerns regarding sensor lifespan, engineering compliance, and industrial integration.
Engineered for high reliability, our hardware range includes shaft monitors, solenoid valves, and central control panels.
