What is a gas detector and what does it do?
What is a gas detector, Wuhan Polyboat Technology to take you to understand what is a gas detector, gas detector is an instrument that can detect the gas, gas detector has a variety of gas detector, such as portable gas detector, fixed gas detector, composite gas detector, a single gas detector, poisonous gas detector, combustible gas detector and so on.
Gas detector can detect the concentration of gases in the environment, such as industrial production of some toxic and hazardous gases or combustible gases, can quickly detect the industrial production of environmental gases in a variety of content of the composition and concentration of the rapid detection of the results. When the environment of combustible or toxic gas leakage, gas detector detects the gas concentration reaches the threshold of the explosion or poisoning alarm settings, the alarm will send out an alarm signal to remind staff to take safety measures.
Gas detector is mainly rely on gas sensors to detect the gas, gas sensors have electrochemical gas sensors, PID gas sensors, infrared gas sensors, catalytic combustion gas sensors, etc., different gases to use different gas sensors to detect the gas concentration. Various gases and various environments use different sensors, most of which can be divided into: sensors for detecting the concentration of toxic gases and sensors for detecting the explosive concentration of combustible gases.
Most of the sensors used to detect the concentration of toxic gases are electrochemical sensors, which are sensors based on electrochemical principles of work, the main influence on its life is the electrolyte, general sensors in 2 to 3 years after the electrolyte is consumed and can no longer work properly, so the service life of the electrochemical sensors is 2 to 3 years. Most of the sensors used to detect the concentration of combustible gases are catalytic combustion sensors, which have a service life of 3 to 5 years.
