Founded in 2003, Xinhaosi Electronic Detection Technology Co., Ltd. has evolved into one of the most influential and reliable brands in the global gas safety industry. Our primary objective is to safeguard every industrial site, municipal network, and residential structure. By implementing advanced electronic sensing technology, we translate unknown atmospheric and chemical hazards into visible, actionable data streams.
Oxygen levels within industrial, laboratory, and marine enclosures dictate operational viability and safety. Whether monitoring oxygen enrichment—which exponentially amplifies combustion hazards—or oxygen depletion, which presents immediate threats to personnel, our gas detection devices deliver absolute accuracy. Backed by our modern, integrated production complex, we develop and manufacture critical monitoring hardware for global buyers, distributors, and engineering contractors under strict OEM and ODM frameworks.
Oxygen gas monitors serve as primary safety components across deep-shaft mines, cryogenic storage units, petrochemical pipelines, and confined workspace configurations. Inadequate monitoring results in undetected asphyxiation hazards, while high oxygen concentrations increase risk of localized flash explosions.
Utilizing liquid or solid-state polymer electrolytes to yield direct linear current proportional to oxygen partial pressure. The latest sensor developments focus on lead-free chemical compositions that comply with RoHS regulations while offering up to 5 years of operational life without drift.
Designed for ultra-high temperature and corrosive gas streams. Paramagnetic oxygen detection leverages the physical magnetic susceptibility of oxygen molecules, providing non-depleting sensing technology ideal for high-purity gas facilities and medical gas generation.
Integrating microprocessors that monitor sensor impedance. By constantly evaluating electrolyte depletion curves and temperature factors, the gas monitors transmit predictive replacement alerts over LoRaWAN, 4G, and RS485 Modbus telemetry networks.
The progression of gas safety engineering points towards autonomous, multi-sensor systems that dynamically adjust their threshold levels based on regional atmospheric parameters. Xinhaosi is actively investing in solid-state electrolyte sensor architectures to minimize temperature-dependent sensitivity drift, enabling reliable operation in Arctic marine environments down to -40°C and desert petrochemical facilities reaching up to 60°C.
Industrial safety is not a one-size-fits-all discipline. Xinhaosi structures its oxygen gas monitors to address distinct environmental challenges across key industrial verticals:
In refining operations, oxygen levels must be strictly monitored to prevent explosions within reactor vessels, inerting blankets, and flare gas recovery systems. High-reliability sensors prevent oxidation reactions from triggering hazardous thermal events. Our flame-proof detectors seamlessly interface with DCS/PLC systems through 4-20mA and HART protocol outputs.
Facilities handling liquid nitrogen, carbon dioxide, argon, or helium require continuous oxygen monitoring. The expansion of these liquids into gas can rapidly displace oxygen, causing sudden asphyxiation. Our wall-mounted detectors feature integrated light and sound alarms, warning staff before they enter low-oxygen zones.
Offshore oil platforms, cargo holds, and ship ballast tanks are susceptible to corrosive saltwater spray and hydrocarbon gas exposure. Designed with saltwater-resistant enclosures, our flameproof oxygen sensors operate under high pressure and humidity, preventing accidents on deep-sea transport vessels.
From initial surface mount technology (SMT) circuit board assembly to automatic calibration chambers, our modern factory utilizes advanced quality assurance protocols to guarantee reliability.
Our manufacturing facility leverages digital automation to guarantee high throughput, consistent calibration, and cost efficiency. As a direct OEM factory, we control the production cycle from raw materials to final calibration, offering significant cost advantages and stable delivery timelines for international distributors.
Our supply chain resilience is supported by deep partnerships with leading electronic component suppliers and sensor chip foundries. This helps protect our production from component shortages and ensures on-time deliveries. Furthermore, our flexible production lines allow us to easily scale production to meet urgent, high-volume orders for major infrastructure projects.
Deploying gas safety systems requires strict compliance with local safety standards and hazardous area classifications. Xinhaosi designs and manufactures products according to international compliance frameworks, simplifying safety validation for global projects.
Our explosion-proof gas detectors and sound-light alarms are engineered to meet ATEX and IECEx specifications, permitting safe installation in Zone 1 and Zone 2 hazardous areas globally.
Designed and verified in accordance with IEC 61508 standards, our monitors achieve SIL2 level safety performance, facilitating integration into safety instrumented systems (SIS).
Through partnerships with localized service providers, we offer field calibration, engineering design, installation assistance, and maintenance support in key regions worldwide.
To support global safety integration, our engineering teams provide complete technical files, including CAD layout drawings, wiring diagrams, and functional safety assessments. This documentation helps EPC contractors and plant engineers gain local administrative approval quickly and run operations smoothly.
Procuring industrial safety systems requires balancing safety and long-term operating costs. Industrial buyers evaluate total cost of ownership (TCO) based on sensor longevity, calibration intervals, replacement part availability, and system integration costs.
Xinhaosi addresses these requirements by building gas monitors designed to optimize lifetime ROI. By using long-life electrochemical and infrared sensors, we extend calibration intervals to 6 or 12 months, reducing the labor and material costs of regular maintenance. Additionally, our modular sensor designs allow technicians to swap sensor elements on-site without removing the transmitter housing, reducing maintenance downtime.
How Xinhaosi minimizes operational costs:
Electrochemical sensors measure oxygen concentration through a chemical reaction that generates current proportional to oxygen levels. They are compact, cost-effective, and ideal for standard safety applications. Paramagnetic sensors rely on oxygen's magnetic properties. Because they don't consume chemical reagents, they are highly stable, drift-free, and suitable for high-temperature and high-purity industrial processes, though they require a larger budget.
Standard safety guidelines recommend checking calibration every 3 to 6 months depending on ambient humidity, dust levels, and chemical exposure. High-stability sensors can extend this interval to 12 months under stable environmental conditions, but periodic bump testing is still recommended to ensure safety.
Depleting electrochemical sensors show signs like output signal drift, slow response times, and failure to calibrate during span adjustments. Xinhaosi smart transmitters monitor internal cell impedance to provide predictive warning alerts, allowing maintenance teams to schedule replacements before sensor failure.
Yes. Our transmitters offer standard industrial signal outputs, including 3-wire 4-20mA analog signals, Modbus RTU protocols over RS485 interfaces, and programmable alarm relays. This allows integration into modern control room architectures.
Our explosion-proof gas safety equipment holds domestic and international certifications, including Ex d IICT6 Gb explosion-proof ratings, SIL2 functional safety ratings, and ISO 9001:2015 quality system certifications. We also offer customization options to help meet local standards in specific target markets.
Xinhaosi Electronic Detection Technology Co., Ltd. officially launched its new Handheld Uncooled Infrared Gas Leak Detector, featuring dual-technology fusion, fast response times, and long-distance detection to enhance safety in chemical plants, cryogenic storage, and municipal gas networks.
We participated in the 5th Western China Cross-Border E-Commerce Expo held in Chengdu. The event connected our technical teams with international procurement managers and global engineering partners, supporting new export opportunities.
