Explore our flagship industrial and residential solutions designed for international market integration and critical environment safety.
Carbon Monoxide (CO) is a highly toxic, colorless, odorless, and tasteless gas, making continuous monitoring an indispensable safety measure across heavy industry, commercial installations, and residential buildings. As a specialized Carbon Monoxide Monitor Manufacturer, our systems utilize premium electrochemical sensors that trigger immediate alarms before toxic gas concentrations reach critical thresholds.
For industrial application scenarios, we engineering explosion-proof housing layouts that are rated for Zone 1 and Zone 2 hazardous areas. Our devices feature robust calibration stability, high selectivity to CO, and zero interference from common organic gases or ambient moisture changes. This reliable output guarantees seamless integration with safety controllers and emergency shut-off gas solenoid valves.
Certified safety integrity level parameters matching standard functional safety models for chemical and refinery pipelines.
Advanced long-life electrochemical elements guaranteeing up to 5 years of stable operations without drift.
Support for RS485 Modbus, 4-20mA, and wireless LoRaWAN / NB-IoT network architectures.

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.
Unrivaled vertical integration, raw materials accessibility, and high-precision automation deliver unmatched economic scale and reliability.
From injection molding and die-casting to SMT circuit boards and CNAS standard calibration, all primary processes are executed in-house. This minimizes supply chain vulnerabilities and ensures consistent pricing stability.
Our dual factories located in Chengdu and Deyang are equipped with automatic assembly lines, advanced gas chamber calibration clusters, and AOI inspection equipment. These facilities operate in strict compliance with ISO9001 and CE directives.
Strategic geographic location coupled with extensive local component vendor partnerships allows us to reduce raw component lead times and pass significant savings directly to global industrial clients.
Global procurement teams seek more than basic detectors; they require robust compliance documentation (SIL, CE, UL, EN 50291) and scalable customization. We serve international partners through tailored services:
The global gas safety industry is transitioning from passive alerts to proactive, data-driven preventative measures. Modern carbon monoxide monitors are increasingly integrated into smart HVAC and building automation systems.

Addressing the core technical, regulatory, and logistics queries that procurement agents and engineers raise during gas detection system integration.
Electrochemical CO sensors have a typical operating life of 3 to 5 years under standard conditions. Factors such as exposure to high temperatures, persistent dry environments, or background chemical solvents can influence sensor lifespan. To counter this, Xinhaosi features built-in self-diagnostic software inside its controllers that warns users prior to sensor depletion.
Explosion-proof detectors (such as the XP3000 or XP4000P) are designed with flame-proof cast aluminum or stainless-steel enclosures that contain internal electrical ignition points. They prevent sparks from escaping and igniting flammable gases in hazardous environments (Zone 1/Zone 2), complying with ATEX, IECEx, and China national explosion-proof standards.
Yes. Our in-house research facilities support comprehensive custom services, including hardware modifications, output interface matching (RS485, 4-20mA, LoRaWAN), custom software configuration, and shell branding. Our ISO9001 and CNAS certified facilities handle everything from design approval to mass production.
CNAS (China National Accreditation Service) accreditation indicates that our testing laboratory satisfies ISO/IEC 17025 requirements. All test data generated is traceable and globally recognized via the ILAC-MRA framework, streamlining international regulatory approvals for regional imports.
When a carbon monoxide detector or combustible gas detector senses concentrations exceeding safety limits, the controller triggers a pulse signal to the solenoid valve. The valve shuts off the gas supply within 0.3 seconds to stop the leak. The valve must be manually reset, ensuring the area is checked and cleared by a technician before restoring gas flow.
Complete control systems, valves, and multi-channel monitoring units designed to complement our carbon monoxide and explosive gas detectors.
