The handheld gas leak detector
With the continuous progress of industry and technology, the handheld gas leak detector, as an important detection tool, has been widely used in various fields. It can detect various gases in real time and accurately, find gas leakage problems in time and deal with them, so as to protect people’s life and property safety. This paper will discuss the versatility of handheld gas leak detectors from many angles, in order to have a deeper understanding of the application and development of the handheld gas leak detector.
Application fiel
The handheld gas leak detector has been widely used in petroleum, chemical industry, metallurgy, electric power, construction, medical and other fields. For example, in the petrochemical industry, handheld gas leak detectors can be used to detect gas leaks in pipes, valves, storage tanks, etc. In the construction industry, it can be used to detect toxic gas leaks in building materials; In the healthcare industry, it can be used to detect gas leaks in medical devices.
The working principle of the handheld gas leak detector
The working principle of handheld gas leak detectors is mainly electrochemical reaction or photoelectric reaction. Electrochemical reaction gas sensors are a method of converting gas concentrations into electrical signals. It consists of two electrodes called working electrodes, one of which is coated with a thin film that can react with the gas being measured. When the gas comes into contact with the electrode, a chemical reaction occurs, creating an electric current. The current intensity is proportional to the measured gas concentration. This sensor can detect a variety of gases, such as hydrogen, carbon monoxide, methane and so on.
The photoelectric reaction gas sensor uses the different absorption degree of different gases to detect the gas concentration. This type of sensor usually consists of a light source and a detector. The light source emits light, and when it passes through the gas being measured, part of the light is absorbed, and the remaining light signal is received by the detector. The degree of absorption is proportional to the concentration of the measured gas. This sensor can detect a variety of gases, such as carbon dioxide, methane, nitrogen and so on.
