In the current various gas detection technologies. Gas detection tools include various gas detectors and various gas detection tubes. Today, I mainly bring you the introduction of toxic and combustible gas detector. Mainly introduce the basic meaning of the portable gas detector. And some basic information. And the classification of portable gas detectors and our choice when choosing portable gas detectors, etc.
Portable gas detector
The first is a gas detector, which is a type of gas detection electronic instrumentation. Mainly used to detect and monitor the concentration of various gases in the environment and their changes. And the test data is displayed on the display screen and stored. In the gas detector. There are mainly two types: portable and fixed. The fixed gas detector is fixed in one place to detect various gas changes in a fixed place. The portable gas detector can be carried with you.
It is usually used for personal safety protection.
Portable gas detector, small size. It is easy to use and can be used by hand. It can also be worn on the chest or on the pockets and caps of clothes. Monitor the concentration changes of various toxic and harmful gases around us at any time. When the detection gas concentration in the environment exceeds a safe value. The portable gas detector will send out various alarm signals. Then we can do all kinds of safety protection work in time.
In a portable gas detector. We can divide this type of gas detector into a single gas detector and a composite gas detector. The main reason is that a single gas detector can only detect one gas concentration, while a composite gas detector can detect two or more. The gas concentration. The main reason is that a single gas detector can only detect one gas concentration, while a composite gas detector can detect tw
