Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, and particularly relates to an environmental monitor. Background Art

[0002] An environmental monitor is a general term for instruments used to monitor various parameters of indoor and outdoor environments. It determines the environmental quality (or pollution degree) and its change trend by measuring representative values of factors affecting environmental quality. A microcomputer laser dust meter is an important instrument for atmospheric environmental monitoring and can monitor the dust concentration in the atmosphere.

[0003] Previous environmental monitors had the following disadvantages: 1. The air inlet could not be automatically rotated to different directions, making it inconvenient to perform gas sampling in different directions. The accuracy of monitoring data was low. It could not automatically dry the moisture in the sampling chamber. Excessive moisture was likely to affect the use of the filter membrane online sampler and even damage it. Therefore, those skilled in the art provided an environmental monitor to solve the problems raised in the above background art. Summary of the Utility Model
