What is a gas detector? Wuhan Juzhou Technology will show you what a gas detector is. A gas detector is an instrument that can detect gas. There are many kinds of gas detectors, such as portable gas detectors, fixed gas detectors, Compound gas detector, single gas detector, toxic gas detector, combustible gas detector, etc.
The gas detector can detect the gas concentration in the environment. For example, there are some toxic and harmful gases or combustible gases in industrial production. It can quickly detect the composition and concentration of various contents in the industrial production environment gas, and quickly detect the results. When the flammable or toxic gas leaks in the environment and the gas detector detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the alarm will send out an alarm signal to remind the staff to take safety measures
Gas detectors mainly rely on gas sensors to detect gas. Gas sensors include electrochemical gas sensors, PID gas sensors, infrared gas sensors, catalytic combustion gas sensors, etc. Different gases need to use different gas sensors to detect gas concentration. of. The sensors used in various gases and various environments are also different, and most of them can be divided into: sensors for detecting toxic gas concentrations and sensors for detecting explosive concentrations of combustible gases.
Most of the sensors used to detect the concentration of toxic gases are electrochemical sensors, which work based on the principle of electrochemistry. The main factor that affects its life is the electrolyte. After 2 to 3 years, the electrolyte can no longer be consumed. It works normally, so the service life of the electrochemical sensor is 2 to 3 years. Most of the sensors used to detect the concentration of combustible gas are catalytic combustion sensors, which have a service life of 3 to 5 years.
