Engineered for high sensitivity, precise calibration, and structural reliability under wide temperature thresholds.
Finland presents a unique landscape for domestic and commercial gas installations. While natural gas pipelines serve primary industrial hubs and urban housing estates in cities like Helsinki, Espoo, and Tampere, liquefied petroleum gas (LPG) remains a core heating and utility fuel source across rural municipalities, summer homes (mökit), and light commercial structures. Under the strict guidelines of the Finnish Safety and Chemicals Agency (Tukes) and the standard SFS-EN 50194-1 for combustible gas detection, safety hardware must operate flawlessly under severe temperature oscillations.
The Finnish climate demands gas detection equipment that incorporates real-time temperature and humidity compensation. Standard detectors often yield false positives in winter environments when indoor heating dries the air, or false negatives in poorly insulated utility sheds during sub-zero operations. Xinhaosi’s premium gas alarms are tested and certified to deliver linear measurement accuracy from -20°C up to +50°C, ensuring compliance with both the SFS standard and regional energy efficiency goals.
Globally, the gas safety industry is transitioning rapidly from stand-alone alarms to integrated, active shut-off systems. Regulatory bodies worldwide are moving beyond simple detection toward active suppression systems—linking a household combustible gas alarm directly to a solenoid valve positioned at the gas meter inlet. In the event of a minor leak, the system immediately cuts the fuel line, averting structural damage and life safety hazards.
Simultaneously, the demand for IoT integration has surged. B2B buyers, real estate developers, and municipal utility companies in Northern Europe increasingly select gas detectors that support network interfaces such as RS485 Modbus, Wi-Fi, or LoRaWAN. This enables multi-unit residential towers to monitor common utility basements, boiler rooms, and Individual heat exchangers from a unified dashboard, decreasing manual inspections and providing insurance-compliant safety audits.
Our Deyang and Chengdu production facilities in Sichuan, China, utilize fully automated surface-mount technology (SMT) and robot-assisted sensor calibration lines to produce millions of stable units annually. This degree of industrial automation minimizes manual error and allows us to maintain strict quality standards at an optimized cost curve.
How Xinhaosi Gas Alarms protect Finnish residential structures, remote cabins, and district utilities.
Integration of OEM JT-AT2004BII Bus-type gas detectors in multi-tenant structures using district methane utilities. Centralized panels allow property managers to monitor gas line safety remotely, satisfying SFS safety metrics.
LPG bottle leakage protection in remote, winterized cabins. The JT-AT2007 features cold-start compensation down to -20°C, triggering an automatic shut-off valve to lock gas cylinders when cabins remain empty.
Deploying the heavy-duty OEM AT2004BIV-CO Carbon Monoxide monitoring systems. Automatically activates mechanical air extraction fans when CO levels rise from vehicle exhausts, reducing power consumption.
Empowering safety globally with advanced intelligent manufacturing and gas detection technology.

A history of innovation, growing into a major global manufacturer of advanced gas safety systems.
Essential guidance on EN compliance, sensor options, and distribution partnerships for European markets.
Our residential and household alarms are designed, tested, and calibrated in accordance with the European Standard EN 50194-1 (for combustible gases in domestic premises) and EN 50291-1 (for carbon monoxide alarms). In addition, they carry CE and SIL certifications to ensure reliable performance in public safety systems.
Yes. Our premium export models incorporate precise temperature-compensation circuits that ensure linear sensor output across a range of -20°C to +50°C. For industrial settings or unheated utility huts, we configure custom sensors capable of even lower operational thresholds.
We provide models featuring dry contact relay outputs, allowing them to interface with external ventilation fans, alarm panels, or smart home hubs. Additionally, we support modern communication protocols such as RS485 Modbus, Wi-Fi, and custom IoT chip integrations for development projects.
Upon detecting target gas concentrations reaching pre-set limits (typically 7%–10% LEL), the detector outputs a DC 9V–12V pulse to trigger the connected solenoid valve. This instantly cuts off the supply at the main manifold, remaining safely shut until manually reset after correcting the leak.
Yes. As a primary manufacturer, we provide comprehensive OEM/ODM services, including customized shell molds, color adjustments, brand labeling, custom alarm thresholds, and localization of alarm sounds or display text in Finnish and Swedish.
