Portable gas detector can detect the presence of gas
Electrochemical gas detectors are gas detectors that use electrochemical sensors. Since many gases are electrochemically active and can be electrochemically oxidized or reduced, the current generated by this reaction is proportional to the concentration of the reacted gas. , so the composition and concentration of the gas can be detected through this type of reaction. This detection method has high accuracy and fast response. It is mostly used for the detection of toxic gases. However, electrochemical reactions also have different classifications. The following introduces the most commonly used electrochemical reaction modes and principles of electrochemical gas detectors.
A portable gas detector is an instrument used to detect the presence of hazardous gases (flammable, explosive, toxic) in a certain environment. For hazardous gases present in the detected environment. Maintenance is an important task to improve the stability, accuracy and lifespan of testing instruments. It is also an important task to effectively prevent failures.
Portable gas detector can detect gas
The portable gas detector can detect various gases such as hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases. It is widely used in petrochemical, On-site inspection in coal, metallurgy, chemical industry, municipal gas, environmental monitoring and other places.
The service life of portable gas detectors
The service life of a portable gas detector mainly depends on the core component sensor. They can be roughly divided into: sensors that detect the concentration of toxic gases and sensors that detect the explosive concentration of flammable gases. Sensors used to detect the concentration of combustible gases include catalytic combustion sensors, which have a service life of 3 to 5 years. Sensors that detect toxic gases use electrochemical sensors, which generally last 1 to 2 years.
