How far can your gas detector detect jurisdiction?
Users often ask this question and mistakenly think that gas detectors can detect a long distance. In fact, there is a misunderstanding here. Gas detectors, especially fixed gas detectors, are generally diffuse, that is to say, gas Diffusion to the sensor head for gas detection is required for them to detect the concentration. Otherwise, even if the toxic gas is nearby, it will not be detected. To give a simple example: the human sense of smell is a very sensitive organ, which can detect trace amounts of gases in the air to levels above ppb, so sometimes we need to get very close to ask, and sometimes we can smell them far away It is seen that this is due to the direction of air flow and the ratio of concentrations. The gas is dissolved in the atmospheric air. Due to the wind direction flow, it may not be detected by the nearby gas detection equipment. As the gas flows farther away from the gas leakage point, the gas concentration will be lower, so the gas concentration can be detected in the distance. Safety does not mean that all locations are safe, the concentration is so low. There is no strict standard for how far to install one. Only in combination with the situation on site can the location of hazards be distributed reasonably. It is recommended to install one device in a large area of 20m2, or install one device within a range of 10-20 meters.
