Explore our core certified gas detection units, high-pressure regulators, and smart monitoring terminals optimized for continuous industrial and residential safety operations.
How modern enterprise systems mitigate combustible gas risks, comply with occupational safety mandates, and protect critical assets worldwide.
Petrochemical installations are vulnerable to fugitive emissions, pipeline cracks, and vessel overpressurization. Our explosion-proof detectors (rated under SIL and CE parameters) provide real-time monitoring across refinery lines, processing chambers, and containment zones, feeding telemetry data back to centralized SCADA systems via Modbus RTU or wireless protocols.
Distribution across high-pressure municipal gas lines requires continuous pressure monitoring and rapid auto-isolation systems. Utilizing our wireless smart pressure monitors and pneumatic-assisted safety shut-off valves, utilities can implement predictive maintenance alerts, pinpoint micro-leaks, and isolate compromised pipeline segments remotely.
From centralized heating boilers to multi-tenant residential complexes, carbon monoxide and natural gas leaks represent acute residential hazards. We manufacture compact, highly sensitive household combustible detectors integrated with domestic shut-off solenoids, ensuring immediate local alarms and automatic main line shutdown.
Xinhaosi's high-performance gas alarms, detectors, and valve systems are deployed globally. Our engineering is backed by state-of-the-art intelligent manufacturing, CNAS calibration certification, and compliance documentation required by Tier-1 energy corporations and municipal gas suppliers.

Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
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.
Engineered for complex micro-environments, from freezing extraction fields to high-humidity commercial kitchens.
Underground monitoring devices must withstand extreme humidity, variable atmospheric pressures, and mud contamination. Our specialized underground shaft gas detectors feature IP67-rated enclosures, hydrophobic dust barriers, and low-drift catalytic combustion sensors, ensuring reliable uptime without frequent field calibration cycles.
Chemical processing and gaseous fuels loading bays are designated as highly hazardous explosive zones. Our detectors feature rugged cast-aluminum, flameproof housings certified for Class I, Division 1 & 2 environments, providing safe operation even when exposed directly to combustible vapors.
Substation basements and urban service channels require remote data pipelines. By utilizing smart wireless terminals, municipalities can aggregate gas concentration metrics, ambient temperatures, and valve positions to dynamically model network stress via centralized safety software dashboards.
Pioneering intelligent gas safety technologies through modern hardware design and advanced sensor integration.
Next-generation alarm systems will combine catalytic bead, NDIR (Non-Dispersive Infrared), and electrochemical sensor fields. This dual-sensing mechanism isolates false positives triggered by common aerosols or humidity shifts, reducing operational downtime caused by false alarms.
By implementing microcontrollers running predictive drift algorithms, future gas detectors will autonomously diagnose sensor degradation and request localized calibration, minimizing field service checks and maintaining permanent high accuracy.
Future iterations of solenoid valves will integrate dynamic flow detection meters. The mechanism detects drops in downstream pressure, comparing sensor telemetry to identify system micro-fractures prior to actual gas accumulation.
