What are the categories of portable gas detectors

        The current application areas of gas detection technology are becoming more and more extensive. It is not only required to be technically superior to other detection products, but also gradually become lighter in operation. Gas detectors are too large and inconvenient to use. In order to facilitate carrying and use, portable gas detectors are becoming more and more perfect. Portable gas detectors are currently clearly classified into two types: pump suction type and diffusion type.

       The pump-suction gas detector is equipped with a small air pump. Its working mode is that the power supply drives the air pump to extract and sample the gas in the area to be tested, and then the sample gas is sent to the instrument for testing. The characteristics of the pump-suction gas detector are fast detection speed, long-distance measurement of dangerous areas, and safety of maintenance personnel. Other features are the same as the diffusion gas detector.

       The diffusion type gas detector is a method in which the gas in the detection area flows freely in the air and the sample gas flows slowly into the instrument for detection. This method is affected by the detection environment, such as ambient temperature, airflow, etc. The characteristic of the diffusion type gas detector is low cost.

       The working principle of pump-type and diffusion-type gas detectors is basically the same. The sample gas is detected by the instrument's sensor and then amplified and sorted by the circuit to convert it into the corresponding value and display it on the screen. The portable gas detectors produced by Huarui Group in the United States are of various types, small in size, simple to operate and easy to use. They have three alarm signals: sound, light and vibration, which can better meet the needs of different places in the industry.

        Gas detectors provide convenience for many industries such as industry and mining, and can accurately test the safety of the construction environment to ensure the safety of workers.
