Our diversified product portfolio covers industrial & residential gas detection & alarm systems, industrial & household gas solenoid valves, and urban gas pipeline network monitoring systems—all engineered to adapt to complex working environments and strict safety requirements. We produce and sell tens of millions of units annually, catering to a wide range of industries that demand reliable gas detection solutions, including oil & gas exploration and production, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, new energy, steel production, and beverage processing.
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.
How our custom engineering solves the critical challenges of oxygen deficiency and enrichment monitoring across extreme operating conditions.
Utilizes proprietary capillary-barrier liquid electrolyte cells. Ideal for standard industrial ambient monitoring (0-25% Vol or 0-30% Vol). These sensors offer fast response times (T90 < 15 seconds) and low power consumption, making them standard in personal monitors and localized transmitter loops.
Operating Temp: -20°C to +50°CEngineered for high-temperature applications (up to 400°C) such as flue gas analysis and combustion control. A zirconia ceramic tube coated with platinum electrodes generates a Nernst voltage relative to the oxygen differential. Unmatched long-term stability without calibration drift.
Lifespan: > 5 Years in harsh environmentsExploits the paramagnetic properties of oxygen molecules to measure concentration with lab-grade precision. Highly stable, non-depleting, and immune to sensor poisoning. Optimal for medical gases, pure gas certification, and critical process monitoring.

Custom gas safety and valve networks tailored for the world's most demanding process safety landscapes.
In offshore drilling and hydrocarbon processing, oxygen deficiency is an immediate threat due to nitrogen purging, while oxygen enrichment poses severe combustion risks. Our flame-proof transmitters with redundant voting architecture ensure continuous process uptime and emergency shutdown (ESD) synchronization.
Oxygen blast furnaces and gas recovery systems require robust detection systems. Our industrial-grade transmitters operate reliably under intense heat, vibration, and dust, safeguarding workers against sudden gas leaks or hazardous build-ups during refining processes.
Cleanroom environments utilizing inert gas blankets (Nitrogen, Argon) require ambient oxygen monitoring to prevent suffocation risks. Our low-profile wall mount transmitters integrate seamlessly with BMS (Building Management Systems) via Modbus RTU or BACnet protocols.
With the completion of our state-of-the-art Deyang factory alongside our headquarters in Chengdu, Xinhaosi operates on full-scale Industry 4.0 principles. We implement highly automated Surface Mount Technology (SMT) lines, selective wave soldering, automated optical inspection (AOI), and multi-stage functional testing matrices. This high level of automation reduces human error, increases yield rates, and keeps production costs highly competitive on the global market.
For global OEMs, this means rapid scalability. Whether you require a custom batch of 100 explosion-proof gas transmitters or an annual supply of 500,000 household gas detectors, our supply chain guarantees reliable component sourcing, redundant manufacturing facilities, and rapid customs clearance through verified logistics pipelines.
