What is the difference between the application of gas alarm diffusion type and pump suction type?

Gas alarms are involved in safety protection issues in enterprises and society , so they have attracted more and more attention from people. Especially in recent years, various departments are paying attention to the severity of safety production. At the same time, enterprises are also based on their own needs in various aspects. , installed a large number of various gas alarm equipment. Due to the different application occasions, two kinds of diffusion type and pump suction type are distinguished.

Gas alarms are divided into diffusion type and pump suction type from the way of obtaining gas samples, and should be correctly selected to meet the requirements of on-site detection.

Only through the natural diffusion of toxic and harmful gases, the gas components reach the gas sensor on the Detector to achieve the detection purpose, which is called a diffusion instrument. Its biggest advantage is that it truly reflects the natural state of the gas in the environment. Therefore, the enterprise When choosing a personal protective Gas Detector for personal protection or a fixed instrument for on-site detection, a diffusion Gas Detector should be selected.

When the inspectors cannot reach or cannot reach the place when detecting the concentration of toxic and harmful gases, they should use pump-suction instruments. Its working principle is to use an external suction pump or an integrated suction pump to extract the The gas is introduced into the detection instrument for detection.
