What are the categories of portable gas detectors?
The current application fields of gas detection technology are becoming more and more broad. Not only are they required to be technically superior to other detection products, they are also gradually becoming lighter in use and operation. Gas detectors are too large and inconvenient to use. In order to be easy to carry Convenient to use, portable gas detectors are becoming more and more perfect. Portable gas detectors are now clearly classified into pump-type and diffusion-type.
The pump-type gas detector is an instrument equipped with a small air pump. Its working method is that the power supply drives the air pump to pump and sample the gas in the area to be measured, and then the sample gas is sent to the instrument for detection. The pump-type gas detector is characterized by fast detection speed, long-distance measurement in dangerous areas, and maintenance of personnel safety. Others are the same as diffusion-type gas detectors.
Diffusion gas detectors allow the gas in the detection area to flow freely in the air and slowly flow the sample gas into the instrument for detection. This method is affected by the detection environment, such as ambient temperature, air flow, etc. Diffusion gas detectors are characterized by low cost.
The working principles of pump-type and diffusion-type gas detectors are basically the same. The sample gas is detected by the instrument's sensor and then amplified and converted by the circuit into the corresponding value and displayed on the screen. The portable gas detectors produced by Huarui Group in the United States have many types, are small in size, simple to operate, and easy to use. They have three alarm signals: sound, light and vibration, and can better meet the needs of different places in industry.
Gas detectors provide convenience for many industries such as industry and mining, and can accurately test the safety of the construction environment. Ensure the safety of workers during construction.
