Fixed Gas
Detector Detection Method Natural diffusion
is to use natural air flow to slowly flow the gas into the instrument for
detection as the air flows freely, so as to obtain the results. Natural
diffusion can accurately check whether the air contains toxic and harmful
substances in real time. It is generally used in open places, such as open
workshops. This method is affected by the detection environment, such as
ambient temperature, wind speed, etc.
