4TECHNICAL INDEX

5、Working principle

1) Working principle of dust detection

Capture the weight of particulate matter in the air through a filter membrane clamp at a specified air flow rate for a certain period of time.

2) Principles of harmful gas measurement

Measure the concentration of harmful gases adsorbed by activated carbon tubes or solutions within a certain period of time by passing a specified air flow rate through activated carbon tubes or a certain volume of solution.
