The portable gas detector is an instrument that can continuously detect the concentration of oxygen and toxic and harmful gases in the working environment. According to the different sampling methods of the instrument, portable detectors can be divided into natural diffusion type and pump suction type. The differences between these two sampling methods are as follows:
1. Natural Diffusion Gas Detector
The gas in the detection area flows freely with the air, and slowly flows the gas to be detected into the instrument for detection. The detector with this sampling method is called a natural diffusion gas detector.
This sampling method is easily affected by the environment, such as ambient temperature, wind speed, etc., and is not suitable for detecting gas sources with low pressure. However, the cost of the diffusion gas detector is lower than that of the pump suction type.
2. Pump suction gas detector
The pump-suction gas detector has a built-in gas sampling pump in the instrument. During the detection, the sampling pump is turned on to sample the gas in the area to be measured, and then the sample gas is sent into the instrument for detection.
The pump-suction gas detector is characterized by fast detection speed and long-distance detection of dangerous areas to protect the safety of workers.
