What do LEL%, VOL% and PPM mean in gas detectors?

What do LEL%, VOL% and PPM mean in gas detectors?

2025-03-15

In order to ensure safe production, gas detectors are widely used in various industries. Gas detectors can monitor the leakage concentration of toxic and harmful gases and flammable gases in the air in real time, effectively preventing the occurrence of various accidents such as fires, explosions and poisonings. When using gas detectors in daily life, users will find that the detection range on the instrument label often shows similar figures such as 0 - 100LEL% or 0 - 2000PPM. Or on the LCD screen of the gas detector, VOL% or PPM may also appear. What do these three units specifically mean and how do they convert among each other?

What is hydrogen sulfide and how toxic is this gas?

2025-02-25

A flammable acidic gas, colorless, can form an explosive mixture when mixed with air, and can cause combustion and explosion when exposed to open flames and high heat energy. At low concentrations, there is a foul egg odor, and at extremely low concentrations, there is a sulfur odor, which is highly toxic.

Hydrogen gas at room temperature and pressure is a colorless, odorless, highly flammable, and insoluble gas in water. Hydrogen is lighter than air, and when used and stored indoors, leaks can rise and accumulate on the roof, making it difficult to discharge. When exposed to a fire source, it can cause an explosion. Hydrogen is listed in the list of hazardous chemicals and is controlled in accordance with the Regulations on the Safety Management of Hazardous Chemicals.

Oxygen is an essential gas for our survival. Normally, the concentration of oxygen is normal, but in some enclosed environments with poor ventilation, there may be situations of oxygen enrichment or hypoxia. When the oxygen content exceeds the normal concentration we accept, accidents can occur once a person is in such an environment.

Application of Toxic and Harmful Gas Alarm in VOC Detection

Application of Toxic and Harmful Gas Alarm in VOC Detection

2025-01-17

VOC is the abbreviation for volatile organic compounds. Generally speaking, VOC refers to volatile organic compounds. However, in terms of environmental protection, VOC refers to a type of volatile organic compound that is active and harmful. So we know that VOC is a harmful gas substance. Before understanding how to scientifically detect VOC, we need to know what harm VOC can cause to both the human body and the environment?
