Overview

Indoor Air Quality Monitor LMAQM-A115 covers broad measurement spans for CO₂, particulate matter, formaldehyde, and TVOC to support indoor conditions. Initiated with NDIR sensor, that tracks carbon dioxide concentrations from 400 to 5000 ppm. Equipped with laser scattering method, which detects particulate matter across fine and coarse ranges. Integrated with electrochemical and semiconductor sensors, it identifies formaldehyde and multiple volatile compounds. Our Monitor supports indoor air quality evaluation in residential rooms, workspaces, and classrooms.
