Pumping and diffusion of gas detector works basically the same, through the instrument of the sensor on the sample gas detection, and then through the circuit amplification into the corresponding value displayed on the screen, combustible gas commonly used catalytic combustion sensor, toxic gas Commonly used electrochemical sensors.
Pumped gas detector is the name of the instrument is equipped with a small air pump, the work of the way the power pump to pump the area of the gas to be sampled, and then the sample gas into the instrument for testing.
Pump gas detector is characterized by fast detection, dangerous areas can be long-range measurement, maintenance personnel safety, and other is same as diffuse gas detector
Diffused gas detector As the name suggests is the gas in the area to be detected With the free flow of air slowly into the instrument into the instrument for testing, this way by the detection of environmental impact, such as ambient temperature, wind speed and so on.
Pumping is suitable for special occasions, such as: people should not go in, or difficult to go into the tunnel, pipes, sewers, tanks, sealed containers and other gas concentration detection, such as oxygen detection, methane detection, carbon monoxide detector, hydrogen sulfide Alarm, combustible gas alarm and other gas detection equipment.
