Are there any combustible gas concentration detectors suitable for use in air ducts?

The wind speed might be high; will it be useful? Automatic air supply is provided when the gas concentration is high, in order to reduce it
This really exists in our factory’s VOC control project, but it’s hard to say whether it’s effective or not.
It should be possible. Take the four-in-one detector as an example – it is used for online analysis of data. As for adjusting the air flow based on the detection results, it’s likely that this detection method using a four-in-one detector won’t work in such cases
If you use direct insertion, it won’t work, as the wind speed is high; such measuring instruments generally employ a diffusion-based measurement method. Therefore, you can consider adding a flow guiding device, along with a pressure-reducing or buffering device in between, before taking samples for measurement. The gas that has been measured can then be returned to the main pipeline
The combustible gas alarm must have realized that the air has been blown away several hundred meters away: lol. \"Automatically supplying more air when the gas concentration is high in order to reduce it\" – this approach is a bit dangerous!
