The main component of natural gas is methane, which is a flammable and explosive gas. If natural gas leaks encounter open flames, static electricity, lightning, or improper operation, explosions and fires may occur, and people in a confined space will lack oxygen, suffocate, and even die. Installing natural gas alarms can effectively prevent explosions and […]

Principles of Gas Sensors
The key component of a gas detector is a gas sensor. Gas sensors can be divided into three categories in principle: Gas sensors using physical and chemical properties: such as semiconductor type (surface control type, volume control type, surface potential type), catalytic combustion type, solid thermal conductivity type, etc. Gas sensors using physical properties: such […]
Principle of Infrared Gas Analyzer
The principle of infrared gas analyzer is to use infrared to analyze the body. It is based on the difference in the concentration of the components to be analyzed and the absorbed radiant energy. The remaining radiant energy makes the temperature rise in the detector different, and the pressure on the two sides of the […]
Precautions in Using the Oxygen Analyzer
When performing oxygen content analysis, especially trace oxygen analysis, because the oxygen content in the air is as high as 21% O2, if it is improperly handled, it will easily cause pollution and interference to the sample, and the analysis result data will be incorrect. The main reason is the improper operation of the oxygen […]
Precautions for Using the Oxygen Analyzer
When the oxygen analyzer performs oxygen specific gravity analysis, especially trace oxygen analysis, because the specific gravity of oxygen in the gas is as high as 21% O2, if it is not handled properly, it will easily cause contamination and interference to the sample, resulting in incorrect analysis result data. The reason is caused by […]
