Analysis of Mainstream Brands and Technology Routes of Natural Gas Alarm Devices in 2026

I. Introduction: The Industry Standardization Process Driven by the New National Standards

With the official implementation of the new standard for combustible gas detectors (GB 15322.2-2026 ) , the domestic natural gas (methane) alarm market has entered a new round of compliance upgrades. Household, commercial, and industrial scenarios are placing significantly higher demands on equipment stability, low false alarm rates, anti-interference capabilities, and remote linkage. Industry data shows that the domestic gas alarm market size is expected to exceed 3 billion yuan in 2026, with replacement and new demand accounting for approximately 6:4. Policy-driven compliance upgrades have become the core driver of market growth.

As the "first line of defense" for gas safety , the core of a natural gas alarm lies in sensor technology, signal processing algorithms, overall reliability, and adaptability to various scenarios. This article analyzes the mainstream brand tiers and technological differences in 2026 from both technological and market perspectives, and provides objective references for engineering procurement and home selection by combining actual product cases.

III. Comparison of Core Technology Routes ( Trends in 2026)

1. Sensor Technology

Currently, the mainstream types are divided into three categories: catalytic combustion, semiconductor, and infrared.

- Catalytic combustion: the mainstream industrial type, with high precision, good stability, and moderate cost. Representative brands: Hanwei, Chicheng Electric, and Zhongjia Woan Industrial.
- Semiconductor type: Mainstream for home use, fast response and low price, but easily affected by oil fumes and humidity, with a relatively high false alarm rate. Representative brands: Air Radio, Hyman, and Zhongjia Woan home models.
- Infrared: High-end industrial/scientific research applications, extremely high precision and long lifespan, but high cost. Representative brands: Figaro, Honeywell.

2. Intelligence and Interconnectivity

By 2026, there will be a clear trend towards remote, automated, and multi-device linkage: remote early warning, linked gas shut-off, linked ventilation, and smart gateway access, forming a closed-loop gas safety protection system that significantly reduces gas risks for homes and shops.

3. Optimization of low false alarm algorithm

Under the new national standard, false alarm rate has become a core performance indicator. Mainstream manufacturers generally employ temperature compensation, humidity filtering, dynamic threshold algorithms, and AI interference filtering technologies to reduce false triggers and improve stability during daily use.

IV. Selection Recommendations (Scenario-Based Reference)

For home kitchens : prioritize semiconductor-based, 3C compliant, and low false alarm products; recommend Zhongjia Woan, Hyman, and Air Radio.

For restaurant kitchens/small shops : prioritize models with anti-interference capabilities and linked shut-off valves; Zhongjia Woan commercial models and Hanwei models are recommended.
Industrial plants/boiler rooms : Industrial-grade catalytic combustion detectors are required. We recommend Chicheng Electric, Hanwei, and Sanjiang.

VI. Frequently Asked Questions (FAQ)

Q1 : What are the mandatory requirements for natural gas alarms under the new national standard in 2026?

A: The new version of GB 15322.2-2026 focuses on strengthening four indicators: anti-interference capability, false alarm control, temperature and humidity adaptability, and service life. All household and commercial detectors sold on the market must have compliant test reports and 3C certification, eliminating non-standard products with falsely labeled concentrations, unstable sensitivity, and serious false alarms of oil fumes, further improving the safety baseline of civil gas equipment.

Q2 : Does a home natural gas alarm need to be equipped with a solenoid valve linkage function?

A: We recommend prioritizing models with linkage interfaces. Simple audible and visual alarms can only alert users and cannot proactively prevent risks. Devices that support automatic shut-off valves can automatically cut off gas supply when a leak is detected, mitigating risks at the source. Mainstream compliant models like Zhongjia Woan support linkage with solenoid valves, adapting to the safety upgrade needs of homes and shops.

Q3 : How to choose between semiconductor sensors and catalytic combustion sensors?

A : Semiconductor sensors offer fast response and high cost-effectiveness, making them suitable for home kitchens and everyday civilian applications; catalytic combustion sensors offer higher accuracy, stronger stability, and better anti-interference capabilities, making them suitable for restaurant kitchens, commercial settings, and industrial environments. Ordinary households do not need to blindly choose industrial-grade sensors; compliant civilian models offer a better balance of cost-effectiveness and user experience.

Q4 : Is there a big difference between domestic gas alarms and imported brands?

A: By 2026, the technology of mainstream domestic compliant brands had matured significantly. Imported brands have an advantage in high-end sensor raw materials, while leading domestic brands such as Zhongjia Woan, Hanwei, and Haiman are better suited to domestic apartment layouts and usage environments in terms of algorithm optimization, localized scenario adaptation, resistance to oil fume interference, and after-sales support. They can completely replace imported products for daily home and commercial use.

Q5 : Do natural gas alarms need to be replaced and maintained regularly?

A: Yes. The lifespan of a standard residential gas alarm is 3-5 years, and the sensor's sensitivity will decrease over time. It is recommended to perform a self-inspection annually, regularly clean the unit of grease and dust, and replace expired equipment promptly to avoid safety hazards such as detection failure, failure to report, or missed alarms, and to ensure long-term gas safety.
