Gas detector is an instrumentation tool for measuring the concentration of gas leaks. It mainly refers to handheld/fixed gas detectors. Gas sensors are mainly used to detect the types of gases present in the environment.
Gas detectors have a wide range of applications, covering industries, agriculture, transportation, science and technology, environmental protection, national defense, aerospace, and daily life. In general, industrial process gas monitoring and analysis instruments are classified in the field of analytical instruments. Common gas detection instruments and meters are usually miniaturized, portable or fixed, work independently or connected to a network, and are widely applied to petroleum, chemical, metallurgy, mining, pharmaceutical, and semiconductors. Processing, spraying, packaging and other industrial sites and homes, shopping malls, liquefied gas stations, gas stations, gas stations and other civil/commercial fire and explosion prevention, prevention of poisoning, air pollution, and agricultural greenhouse gas detection, biogas analysis and biogas security monitoring and Environmental emergency accidents, terrorist attacks, storage and transportation of dangerous goods.
Gas detector selection principle:
First, specify the purpose of the test, select the type of instrument In short, the detection of harmful gases has two purposes, the first is the test explosion, and the second is the drug detection. The so-called explosion test is to detect the gas content of dangerous places and exceed the standard alarm so as to avoid the occurrence of explosion accidents; the detection of poisons is to detect the contents of all poisonous gases in dangerous fields and exceed the standard alarm so as to avoid poisoning by workers. The range of explosion detection is 0-100% LEL, and the range of poison detection is 0-several (or several hundred) ppm. There is a big difference between the two.
There are three kinds of hazardous gases in hazardous areas: first, non-toxic (or low-toxicity) flammable, second, non-flammable, toxic, and third, flammable and toxic. The first two conditions are easy to determine, the first test explosion, the second test poison, the third case if there is a person exposed to test poison, if no personnel exposure can be measured. Select the combustible gas detection alarm device for the explosion test, and select the toxic gas detection alarm device for the poison detection.
Second, specify the detection purposes Select the type of instrument (portable or fixed) Production or storage positions for long-term leak detection using fixed detection alarm; other like maintenance inspection, emergency detection, entry detection and inspection and other optional portable (or pocket type )instrument. The model number of the instrument includes the three main contents of the manufacturer, function index and detection principle.
