Description

The UNI-T A25D is a compact air quality monitor for use in living spaces, offices, or commercial areas. The focus is on measuring PM2.5 fine dust concentration in a range of 0–500 µg/m³, making it easy to quickly identify changes in air quality. Additionally, the device provides reference values for formaldehyde, temperature, and relative humidity.

Automatic baseline calibration as well as audible and visual alarms allow the measuring device to be used without technical knowledge. The backlit display with a size of 42 × 65 mm remains easy to read even in poor lighting conditions, while automatic power-off and low battery indication make daily use convenient. The monitor is powered by a 1500 mAh polymer battery.
