Two Types of Portable Gas Detectors
The current application field of gas detection technology is getting wider and wider. Not only is it required to be superior to other detection products in technology, but it is also gradually lighter in use and operation. The portable gas detector is too large and inconvenient to use. In order to facilitate Portable and easy to use, portable gas detectors are becoming more and more perfect. At present, portable gas detectors also have a clear classification, which is divided into two types: pump suction type and diffusion type.
The pump-suction portable gas detector is equipped with a small air pump. Its working method is that the power supply drives the air pump to extract and sample the gas in the area to be measured, and then send the sample gas into the instrument for detection. The pump-suction portable gas detector is characterized by fast detection speed, long-distance measurement of dangerous areas, and maintenance of personnel safety. Others are the same as the diffusion portable gas detector.
The diffusion type portable gas detector is that the gas in the detection area flows freely in the air and slowly flows the sample gas into the instrument for detection. This method is affected by the detection environment, such as ambient temperature, airflow, etc. Diffusion portable gas detectors are characterized by low cost.
The working principle of the pump suction type and the diffusion type portable gas detector is basically the same. The sample gas is detected by the sensor of the instrument, and then the corresponding value is displayed on the screen after being amplified and sorted by the circuit. Huarui Group of the United States produces portable gas detectors with various types, small size, simple operation and convenient use. It has three alarm signals of sound, light and vibration, which can better meet the needs of different places in the industry.
Portable gas detectors provide convenience for various industries such as industry and mining, and can accurately test the safety of the construction environment. Ensure the safety of workers during construction.
