What are the gases that can be detected by a portable gas detector?
Electrochemical gas detector, is the use of electrochemical sensors of the gas detector, due to a lot of gas can be electrochemically active, can be electrochemical oxidation or reduction, and the current generated by this reaction and the reaction of the gas concentration into a certain ratio, so can be detected through this type of reaction of the composition and concentration of the gas. This detection method is highly accurate, fast response, mostly used for toxic gas detection, but the electrochemical reaction also has different classifications, the following introduces the electrochemical gas detector * commonly used several electrochemical reaction mode and principle.
Portable gas detector is used to detect the presence of dangerous gases (flammable and explosive, toxic) in a certain environment. For the presence of dangerous gases in the environment detected. Maintenance is to improve the stability of the detection instrument, accuracy and life of the important work. It is also an important work to effectively prevent failure.
Portable gas detector can detect gas
Portable gas detector can detect hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases and other gases, widely used in petrochemicals, coal, metallurgy, chemical industry, municipal gas, environmental monitoring, and other places of on-site testing.
Service life of portable gas detector
The service life of portable gas detector mainly depends on the core component sensor. Roughly can be divided into: detection of toxic gas concentration sensors and sensors used to detect the explosive concentration of combustible gases. Sensors used to detect the concentration of combustible gases have catalytic combustion sensors, which have a service life of 3 to 5 years, and sensors for detecting toxic gases are electrochemical, generally 1 to 2 years.
