What are the classifications of convenient gas detectors
The current application fields of gas detection technology are becoming increasingly broad, not only requiring technical superiority over other detection products, but also gradually becoming lighter in use and operation. Gas detectors are too large and inconvenient to use. In order to facilitate portability and use, portable gas detectors are becoming more and more perfect. Portable gas detectors are now clearly classified into two types: pump suction and diffusion.
The pump suction gas detector is equipped with a small air pump, which works by driving the power supply to sample the gas in the test area, and then sending the sample gas into the instrument for detection. The characteristic of a pump suction gas detector is its fast detection speed, which can measure dangerous areas from a distance, maintain personnel safety, and is similar to a diffusion type gas detector.
A diffusion gas detector is a device that detects the gas in the detection area by slowly flowing the sample gas into the instrument in the air. This method is influenced by the detection environment, such as ambient temperature, airflow, etc. The characteristic of diffusion gas detectors is low cost.
The working principle of pump suction and diffusion gas detectors is basically the same. The sample gas is detected through the sensor of the instrument, and then amplified and converted into corresponding numerical values for display on the screen. The portable gas detectors produced by Huarui Group in the United States have a wide range of types, small size, simple operation, and convenient use. They have three types of alarm signals: sound, light, and vibration, which can better meet the needs of different places in industry.
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.
