When ammonia is mentioned, most people first think of its pungent smell in public restrooms. This unpleasant odor is only the most superficial aspect of ammonia. Behind this colorless gas lies both an industrial miracle that feeds billions of people worldwide and a dark history of deadly dangers and war.

It is a typical "two-sided gas"—both "useful" and "toxic".

Combustible gas detectors are the first line of defense against gas accidents, but various malfunctions are inevitable during long-term use. When the malfunction indicator light illuminates and the alarm continues to sound, how can you quickly and accurately troubleshoot the problem? This article compiles common malfunction symptoms and corresponding solutions to help you quickly locate the issue.

In industrial sectors such as petrochemicals, gas transmission and distribution, wastewater treatment, and mining, gas detectors are the first line of defense for ensuring personnel safety and continuous production. However, faced with a dazzling array of product types, sensor technologies, and performance parameters on the market, choosing an industrial detector that truly suits one's specific operating conditions often leaves purchasing personnel and safety managers perplexed.

Choosing the wrong detector can lead to anything from frequent false alarms disrupting production to missed alarms causing safety accidents. This article will provide you with a systematic selection method based on the latest standards, including GB/T 50493-2019 "Design Standard for Combustible and Toxic Gas Detection Alarms in Petrochemical Industry" and GB/T 46692.2-2025 "Gas Detectors for Workplace Environments Part 2: Selection, Installation, Use and Maintenance of Toxic Gas Detectors" which will be implemented in May 2026.

In fields involving the monitoring of flammable and explosive gases, such as petrochemicals, mining, gas transmission and distribution, and industrial manufacturing, gas detectors are the "first line of defense" for ensuring safe production. For a long time, catalytic combustion sensors have dominated the field of combustible gas detection due to their simple structure and low cost. However, with the increasing complexity of industrial scenarios, stricter safety standards, and accelerated technological iteration, infrared sensing technology based on the non-dispersive infrared (NDIR) principle is gradually replacing traditional catalytic combustion sensors and becoming the mainstream direction for industry upgrades.

This article will systematically analyze the inherent logic and underlying motivations of this technology substitution trend from the perspectives of technical principles, core performance, application scenarios, and economic efficiency.

In a corner of the city, chefs are busy preparing dinner in the kitchen of a restaurant; in a remote petrochemical industrial area, pipes crisscross and machines roar; in the basement of a residential building, gas pipes quietly run through the walls... In these scenes, an unseen "guardian" is working silently—it is the gas detector.

A single instrument can perform three-dimensional monitoring of 490 types of polluting gases and complete leak detection in 200 milliseconds.

Recently, the Infrared Precision Instruments Team of the Anhui Institute of Optics and Fine Mechanics (Anhui IOM), Hefei Institutes of Physical Science, Chinese Academy of Sciences, announced exciting news: they have achieved a systematic breakthrough in the field of gas remote sensing three-dimensional imaging technology, successfully constructing a three-dimensional detection network for leaked gas and realizing infrared remote sensing three-dimensional imaging of gas concentration and composition information. This achievement marks that China has reached an internationally leading level in the field of gas monitoring technology , providing a brand-new technical means for fields such as chemical safety and environmental protection.

Recently, the State Administration for Market Regulation (National Standardization Management Committee) approved and released two mandatory national standards: "Combustible Gas Detectors Part 1: Point-Type Combustible Gas Detectors for Industrial and Commercial Use" (GB 15322.1—2026) and "Combustible Gas Detectors Part 2: Household Combustible Gas Detectors" (GB 15322.2—2026). These two standards are under the jurisdiction of the Ministry of Emergency Management and will be implemented by the Fire Detection and Alarm Subcommittee of the National Fire Protection Standardization Technical Committee. They will officially come into effect on August 1, 2027 .

Early spring comes to those who work diligently; now is the time to strive forward. On the tenth day of the first lunar month, while festive New Year cheer still filled the streets of Zhuhai, Zhuhai Chuang'an Electronics Technology Co., Ltd., located in the Science and Technology Industrial Park on Meihua West Road in Xiangzhou District, was already bustling with activity. As a pioneer in China's gas detection industry, Chuang'an Electronics officially sounded the “call to action” for resuming work and production in the Year of the Snake. All employees returned to their posts with full enthusiasm, striving to achieve a strong start to the new year.
