Software calibration, password protection function;

Equipped with a height adjustable triangular bracket.

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 through activated carbon tubes or a certain volume of solution at a specified flow rate.
