Explore our elite explosion-proof transmitters, multi-channel gas controllers, and low-voltage power supply units designed for heavy industrial environments.
Understanding the delicate balance between high-efficiency operations and toxic hazard mitigation in global commercial processes.
Ammonia ($NH_3$) remains the thermodynamic refrigerant of choice for large-scale logistics, global cold storage chains, food processing, and chemical synthesis. Due to its superior COP (Coefficient of Performance) and zero Ozone Depletion Potential (ODP), the transition to natural refrigerants has accelerated global demand. However, Ammonia is highly toxic at minimal exposure levels (OSHA PEL is just 50 ppm over an 8-hour TWA) and exhibits explosive traits under specific conditions ($15\%$ to $28\%$ by volume in air).
As a global Ammonia Detector Manufacturer, we specialize in high-precision sensing instruments designed to withstand extreme sub-zero environments, chemical washdowns, and high ambient moisture typical of modern manufacturing hubs.
Two decades of engineering gas safety systems that protect millions of lives across industrial and commercial infrastructure.
Chengdu Factory & Office
Deyang Factory
Founded in 2003, Xinhaosi is one of the most influential and trusted brands in the global gas safety industry. Over the past two decades, we have steadily built a robust and comprehensive production and service system, which integrates cutting-edge R&D, intelligent manufacturing with advanced automation equipment, digital marketing across global channels, professional after-sales support with an experienced technician team, flexible OEM/ODM services, as well as CNAS-Accredited laboratory calibration services that meet international standards.
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.
Guided by the core mission of “Making Gas Safety Accessible Everywhere,” we consistently deliver high-performance, reliable products and customized solutions tailored to each client’s unique needs. 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.
Our compliance structure and patent portfolio are designed to provide maximum certainty under regulatory inspection.
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," membership in the China Fire Protection Association, and acts as the main drafting organization for the national standard of solenoid valves, confirming our industry leadership.
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, 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.
Customized architectures designed to address the specific vulnerabilities of distinct commercial processes.
Ammonia systems operate at low temperatures in cold storage. Under freezing conditions (-40°C), traditional electrochemical sensors can experience slow response rates. Our systems utilize integrated internal heating elements and specialized low-temperature electrolyte blends to maintain high sensitivity and fast T90 response times, preventing costly false alarms and product spoilage.
Fertilizer plants and chemical synthesizers often contain corrosive background gases. We incorporate multi-layered chemical filters and selective catalytic bead/electrochemical modules. This prevents cross-sensitivity issues, ensuring that the sensor responds exclusively to targeted NH₃ releases.
With ammonia rising as a prominent carbon-free marine fuel carrier, maritime transport requires robust offshore gas detection. Our marine-grade detectors feature offshore coating protections, vibration-resistant mounting systems, and marine certifications (ABS/DNV standards compatibility).
The technological evolution of Ammonia detection: from analog cells to AI-driven optical systems.
While electrochemical sensors are cost-efficient, they suffer from degradation when exposed to constant background Ammonia concentrations. Our future roadmap integrates Tunable Diode Laser Absorption Spectroscopy (TDLAS). TDLAS provides drift-free operation, immunity to environmental changes, and a lifespan exceeding 10 years without calibration drift.
Modern plants demand data-driven insights. Our intelligent gas controllers now offer real-time telemetry, predictive health indicators for sensor elements, and seamless integration with industrial SCADA systems. By monitoring cell impedance, we forecast sensor degradation before failures occur.
