Description

Air dust monitoring device

Technical Field

The utility model relates to the technical field of air monitoring equipment, in particular to an air dust monitoring device.

Background technique

Existing dust monitoring devices often need to be installed in a fixed area during use. When dust monitoring is required for a certain area of the construction site, the dust monitoring device needs to be reinstalled, which brings trouble to the construction. As the construction process progresses, the pre-installed dust monitoring device will affect the later construction. During the later construction, the dust monitoring device needs to be removed and installed in other locations, which brings trouble to the construction. The bracket of the existing movable dust detection instrument with a bracket is mainly a tripod structure, which is not stable enough and is not suitable for construction sites.
